[PATCH 1/3] nfsd4: delay setting current filehandle till success

["J. Bruce Fields" <bfields@redhat.com>]

From: "J. Bruce Fields" <bfields@redhat.com>

Compound processing stops on error, so the current filehandle won't be
used on error.  Thus the order here doesn't really matter.  It'll be
more convenient to do it later, though.
