AudioRecord: fix AudioRecordThread crash upon exit

In case of error during openRecord_l(), there is a possibility
that a newly created AudioRecordThread is resumed by requestExit()
just after entering the Thread class _threadLoop() but before
entering the class threadLoop(). In this case, processAudioBuffer()
is executed once with mCblk == 0 and we assert.
