irda: iriap: Use seperate lockdep class for irias_objects->hb_spinlock
The SEQ output functions grab the obj->attrib->hb_spinlock lock of sub-objects found in the hash traversal. These locks are in a different realm than the one used for the irias_objects hash table itself. So put the latter into it's own lockdep class.
