Realsense : CameraEqual assertion

[sandeepdutta]

Hello all,
CHECK(CameraEqual) in camera_cache.cc fails when Realsense depth module
is configure with HDR (HDR Merge enable) and align_depth is enabled.
The align depth causes the camera info to change. Temporary fix is to
update the camera_cache with the new values, the module continues to work.
