There are instances, though rare, where a LOGO request
cannot be sent out and the thread in free session done
can wait indefinitely. Fix this by putting an upper
bound to sleep.

Hi Himanshu,
Is qla2x00_async_iocb_timeout() called if no response is received for a
LOGO request? If so, has it been considered to modify that function
instead of qlt_free_session_done()?
Thanks,
Bart.
