Please move the INIT_WORK() call to an initialization function such that
is executed once instead of during every qla2x00_schedule_work() call. Please
also remove the iocb_work_sheduled variable and all code that tests and sets
it. schedule_work() already checks whether or not a work item has been
scheduled.

The != operator has a higher precedence than the && operator so the parentheses
around the inequality test are not needed.
