failed in sp_process_inode_ctx.
We need this patch for following reasons:
1. The inode used in the successful lookup call may not be the one passed to
fops operating on path. This may happen, if revalidate of inode is failed,
but the lookup itself succeeds (in case of reavalidate failures, fuse
sends a fresh lookup using new inode) and since inode_link, if there is an
inode already associated with a path retains it.
2. Only fops that "wait" in stat-prefetch on a lookup which is already in
progress, need to check for the result of the lookup they are waiting on,
before resuming and sp_process_inode_ctx is _not_ used in such contexts.

- since sp_process_inode_ctx is called by many fops, if the context is not
set "caller" argument can be logged in log msgs to identify caller.

lookup on same path if one is in progress.
- If current lookup (2) does not wait for completion of the lookup (1) which
is in progress, there can be a race condition where (2) completes ahead of
(1) and resuming all the waiting operations in the queue. When (1) returns,
the original operation (eg., stat, chmod etc) might've already unwound and
hence the frame would've been destroyed.

not the expected one.
- cache creation is expensive operation. Also, cache will be freed in
releasedir. Hence, just remove all entries from cache without freeing
the cache. However this is not entirely true, since sp_cache_remove_entry
frees the old table and reinitializes a new table if all entries are being
removed. When rbtree based hash table provides an interface to remove all
the entries, sp_cache_remove_entry should be modified not to destroy the
table.
- this patch also fixes a race condition wherein the cache being used in
lookup getting freed in readdir if the offset is not equal to expected
offset.

- distribute picks up the inode number from hashed subvolume. But readdir
is done from different subvolumes based on the offset. Hence there is a
possibility of inode number and device number for directories being
inconsistent between two stat calls.

- this procedure processes inode_ctx to make decisions like whether the
current procedure can continue (i.e., inode is already looked up),
or the procedure has to initiate/wait for lookup on the path. It also
sets up the frame->local and adds the stub corresponding to current fop
if needed.

- change sp_lookup and sp_lookup_cbk to support sending lookups when needed.
lookups might need to be sent in fops like open, chmod, chown etc which
operate on a path, since the actual lookup sent to stat-prefetch by its
parent xlators is not propagated down the xlator tree if the path is
cached.
