Subject: msm8996-common: camera: HAL3: Error occurs while unmapping buffer

Issue:
STL operation such as erase ,push_back needs to be atomic.

List to keep reprocessed meta and buffer is prone to
simultaneous access from other part of codes causing STL
operations to fail.

Fix:
Keeping STL operation of list for buffer and meta both in mutex.
