path_has_submounts(): use guard(mount_locked_reader)

Needed there since the callback passed to d_walk() (path_check_mount())
is using __path_is_mountpoint(), which uses __lookup_mnt().

Has to be taken in the caller - d_walk() might take rename_lock spinlock
component and that nests inside mount_lock.
