Checks added in megasas_queue_command to know if FW is able to process
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.

Why not "bool is_busy:8;"? It obviously is a boolean. I would also think
false/true would be more descriptive then 0/1.
