nfs: Create frames with frame->root as nfsx

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.
