When remounting an NFS or NFS4 filesystem, the new NFS options are not
respected, yet the remount will still return success. This patch adds
a remount_fs sb op for NFS that checks any new nfs mount options against
the existing ones and fails the mount if any have changed.
This is only implemented for string-based mount options since doing
this with binary options isn't really feasible.
What about respecting the new options as makes sense and rejecting
those which absolutely can't be changed dynamically?
