Checks added in megasas_queue_command to know if FW is able to process[snip]
commands within the timeout period. If number of retries is 2 or more,
the driver stops sending cmd to FW. IO is resumed when pending cmd count reduces to 16 or 10 seconds has elapsed from the time cmds were last sent to FW.
