qcacmn: Add spinlock release API in objmgr debug code

Spinlock is locked but not unlocked in objmgr debug code,
this leads to deadlock.
To avoid, while iterating over logically deleted nodes,
if macaddr is NULL (macaddr could be NULL, either due object
memory corruption or object itself is NULL) release list lock
and raise BUG(). Also if name of object (psoc/pdev/vdev/peer)
is NULL (object name could be NULL, if obj_type passed while
adding object to logically deleted list is >= WLAN_OBJ_TYPE_MAX)
release list lock and raise BUG()
