lib/sbitmap: define swap_lock as raw_spinlock_t
When called from sbitmap_queue_get(), sbitmap_deferred_clear() may be run
with preempt disabled. In RT kernel, spin_lock() can sleep, then warning
of "BUG: sleeping function called from invalid context" can be triggered.
Fix it by replacing it with raw_spin_lock.
