rtc: Condition QP adjustment on rc->q_1/2_frame > 0

This fix only affects the initial QPs after very first
frame for TL enhancement frames in CBR mode.
Move the check that rc->q_1/2_frame is set to the top
of the adjustment logic, otherwise if there are dropped
frames after the very first frame, the QP can end up
with oscillation on temporal enhancement frames.

Because of some further logic/adjustments this
behavior would likely only happen when the TL enhancement
frame_bandwidth is not smaller then TL0 frame_bandwidth.
