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.
