    ahc: fix potential NULL deref

    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.
