[PATCH v1 3/4] nfs: Update server port after referral or migration

[Chuck Lever <chuck.lever-QHcLZuEGTsvQT0dZR+AlfA@public.gmane.org>]

After traversing a referral or recovering from a migration event,
ensure that the server port reported in /proc/mounts is updated
to the correct port setting for the new submount.
