ASoC: msm: qdsp6v2: fix for mutex deadlock in listen driver

Listen driver was not unlocking the cal mutex in alloc function.
After alloc function is called sendcal ioctl tries to acquire the lock
and gets blocked.In sendcal function physical address was being checked
instead of payload size.This change fixes listen application hang issue.
