CVS commit: src/sbin/mount_null

Modified Files:
        src/sbin/mount_null: mount_null.c

Log Message:
Eliminate the distinct path check, since the paths don't actually need to be
 distinct and allowing this makes certain useful tasks possible, such as
 fixing an unpopulated /dev while a tmpfs is mounted over it.
However, require the paths to be different, as mounting a path directly over
 itself has the side effect of causing any other mount points within that path
 to no longer be accessible, and is difficult to unmount when done on /.
