Bluetooth: Process interrupt in main thread of btmrvl driver as well
When driver is sending a command or data and the firmware is also
sending a sleep event, sometimes it is observed that driver will
continue to send the command/data to firmware right after processing
sleep event. Once sleep event is processed driver is not supposed to
send anything because firmware is in sleep state after that. Previously
interrupt processing was done in SDIO interrupt callback handler.
Now it is done in btmrvl driver main thread to solve the
cross-sending properly.
