ASoC: msm: qdsp6v2: fix non-gapless transition failure

During non-gapless transition, there is an indefinite wait in
drain until either eos_ack or cmd_interrupt is set. This results
in playback getting stuck and occurs because cmd_interrupt is
not set in TRIGGER_STOP as gapless_transition is set to 1 during
partial drain of earlier stream.

Fix the issue by setting gapless_transition to 0 when gapless
fails which ensures that cmd_interrupt is set in TRIGGER_STOP.
