[SCSI] qla2xxx: only free_irq() after request_irq() succeeds
If qla2x00_probe_one() fails before calling request_irq() but gets to qla2x00_free_device() then it will mistakenly try to free an irq it didn't request. It's chosing to free based on ha->pdev->irq which is always set. host->irq is set after request_irq() succeeds so let's use that to decide to free or not. This was observed and tested when a silly set of circumstances lead to firmware loading failing on a 2100.
