[PATCH 009 of 18] knfsd: nfsd4: pass saved and current fh together into nfsd4 operations.

[NeilBrown <neilb@suse.de>]

From: J.Bruce Fields <bfields@fieldses.org>

Pass the saved and current filehandles together into all the nfsd4 compound
operations.

I want a unified interface to these operations so we can just call them by
pointer and throw out the huge switch statement.

Also I'll eventually want a structure like this--that holds the state used
during compound processing--for deferral.
