dev-amdgpu: Remove duplicate writes to PM4 queue pointers

Browse Source 
During checkpoint restoration, the unserialize() function writes rptr,
wptr, and indirect buffer rptr, wptr to PM4 queue's rptr, wptr fields.
This commit updates this to write only the relevant pointers to the
queue structure. If indirect buffers are used, then it writes only the
indirect buffer pointers to the queue. If they are not used, then it
writes rptr, wptr values to the queue.
