features/shard: Do list_del_init() while list memory is valid

Problem:
shard_post_lookup_fsync_handler() goes over the list of inode-ctx that need to
be fsynced and in cbk it removes each of the inode-ctx from the list. When the
first member of list is removed it tries to modifies list head's memory with
the latest next/prev and when this happens, there is no guarantee that the
list-head which is from stack memory of shard_post_lookup_fsync_handler() is
valid.

Fix:
Do list_del_init() in the loop before winding fsync.
