>Description:
umount(8) claims that we support

	$ umount rhost:path

but a call to realpath(3) early in umount.c:umountfs() fails for rhost:path and
umount returns with an error.

This has another annoying side effect.  swapctl -U tries to umount the swap
mount point using umount rhost:path syntax and fails.
>How-To-Repeat:
Try to umount an nfs-mounted filesystem using umount rhost:path syntax.

>Fix:
Not really a fix, but for swapctl(8) the workaround is to pass
the mount point to the umount:
