I don't think you are right here. That message should appear always,
independently from result of resize. The only reason why it may not
show, is if resize wasn't tried at all due to false result of
INQ_DATA_TQ_ENABLED(&dev->inq_data). In other cases number of openings
should be adjusted, independently from number of running requests (queue
shrinking may be delayed).
