Subject: Fix assert in mjpeg_encoder_adjust_params_to_bit_rate()

If mjpeg_encoder_reset_quality() is called with the same quality as currently
set, it will not reset last_enc_size but not reset num_recent_enc_frames,
violating some assumptions in _adjust_params_to_bit_rate(). To avoid aborting
the server, simply return early from this function.

Resolves: rhbz#1086820
