media: iris: gen1: Destroy internal buffers after FW releases

Browse Source 
After the firmware releases internal buffers, the driver was not
destroying them. This left stale allocations that were no longer used,
especially across resolution changes where new buffers are allocated per
the updated requirements. As a result, memory was wasted until session
close.

Destroy internal buffers once the release response is received from the
firmware.
