NFS: Fix a problem with the legacy binary mount code
commit 872ece86ea5c367aa92f44689c2d01a1c767aeb3 upstream.
Apparently, am-utils is still using the legacy binary mountdata interface,
and is having trouble parsing /proc/mounts due to the 'port=' field being
incorrectly set.
The following patch should fix up the regression.
