media: iris: gen1: Destroy internal buffers after FW releases
[ Upstream commit 1dabf00ee206eceb0f08a1fe5d1ce635f9064338 ]
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.
Fixes: 73702f45db81 ("media: iris: allocate, initialize and queue internal buffers")
