[NFS] [PATCH] NFS: show addr=ipaddr in /proc/mounts rather than

A minor thing, but useful when working with a server with multiple
addrs. This looks like it might also be necessary if Miklos' effort
to eliminate /etc/mtab ever comes to fruition.

When displaying mount options in /proc/mounts, the kernel prints
"addr=hostname". This info is redundant since we already have the
hostname displayed as part of the "device" section of the mount. This
patch changes it to display the IP address to which the socket is
connected.
