av: CAF: kill that log spilling

Change-Id: Idd4ebe8c98aa7100af00c5a9f4fe016a2406a196
camera: Disable extra HDR frame on QCOM_HARDWARE

Qualcomm camera HALs default to adding an extra zero-exposure frame
to HDR snapshots; this is breaking third-party apps, and we don't
use it in system-bundled apps, so disable it unless explicitly
requested by the client

Change-Id: Iecb868c5c344d972de7f36dc1bd9cc9fdbabaf4e
camera: Ignore CAF_RESTART callbacks

 * Ignore these callbacks which are sent by Samsung camera drivers, as
   they can cause a deadlock in normal operation.
