frame root was being set to the subvol on which the fop was to be performed.
Apart from just being totally wrong behaviour, this also messes up
mem-accouting because there THIS points to the wrong xlator resulting in crap
addresses being dereferenced through the mem type index.

Fixes a crash that occurs because the nfs-fops code accesses
a fop local after it has been returned to the mem pool.
Generally seen when nfs load is so high that the mem-pool runs out
of memory and starts CALLOCing.

The current design of the interaction between the generic NFS layer and the
protocol handlers like mount3 and nfs3 is such that it does not allow using a
single volume file which contains the nfs/server and the protocol/server.
This is because the common nfs-fops layer assumes that ctx->top is always the
nfs/server. This is wrong. The fops layer needs access to top because top or
rather the generic NFS xlator's private state has a mem-pool. The fops layer
needs this mem-pool to get memory for storing per-fop state. Since the fops
layer cannot anymore take ctx->top be the nfs/server, all layers need to start
passing the nfs/server xlator_t right down to the fops layer.
I am also taking this chance to remove the synchronous equivalents of the fops
and also remove the dirent caching directory operations.
