mm/slub: convert object_map_lock to non-raw spinlock

The only remaining user of object_map_lock is list_slab_objects().
Obtaining the lock there used to happen under slab_lock() which implied
disabling irqs on PREEMPT_RT, thus it's a raw_spinlock. With the
slab_lock() removed, we can convert it to a normal spinlock.

Also remove the get_map()/put_map() wrappers as list_slab_objects()
became their only remaining user.
