Peter Zijlstra d19c813788 locking/lockdep: Provide lockdep_assert{,_once}() helpers ...

Extract lockdep_assert{,_once}() helpers to more easily write composite
assertions like, for example:

	lockdep_assert(lockdep_is_held(&drm_device.master_mutex) ||
		       lockdep_is_held(&drm_file.master_lookup_lock));
