vfs: fix shrink_submounts
In the last refactoring of shrink_submounts a variable was not completely renamed. So finish the renaming of mnt to m now. Without this if you attempt to mount an nfs mount that has both automatic nfs sub mounts on it, and has normal mounts on it. The unmount will succeed when it should not. Signed-off-by: Eric W.
