Bluetooth: Fix to avoid hci event getting flushed
Fix to to avoid valid hci event for baudrate change getting
flushed while changing local baudrate. SoC is sending event during
flow off,which is not expected by the host. Host as part of baud
rate changes calls tcflush to flush any persistant data. During
this process valid hci event is getting flushed casuing BT on
failure.
