Camera: Ensure background edition complete on back Key

Block back key event till the image will get displayed
while user pressed edit option/icon. This'll allow the
background process to cleanup memory. Added null check
and bitmap recycle to avoid crash.

Camera: Fix out-of-order operations while setting up the editor

The buffer's producer is created by the cache pipeline generation,
so verifying that it isn't null before calling compute() is wrong.

This breaks a few devices, and should actually break them all, so
fix it; only check if getProducer() is valid after running setProducer()
