ahc: fix potential NULL deref

Browse source 
This bug was found via cppcheck static analysis.

If android.hardware.Camera.getParameters returns NULL, then object will
be NULL, and we won't allocate params. This means that the GST_DEBUG
statement referencing params->object will be invalid. Fix this by
exiting early if android.hardware.Camera.getParameters returns NULL.
