Subject: [PATCHv3] qla2xxx: Correct compilation issues when
 CONFIG_MODULES=n.

Randy Dunlap noted:

  when CONFIG_MODULES=n:

	drivers/scsi/qla2xxx/qla_os.c:2685: error: dereferencing pointer to incomplete type

  in

	kobject_uevent_env(&(&vha->hw->pdev->driver->driver)->owner->mkobj.kobj,
		KOBJ_CHANGE, envp);

Trigger kobject event on the 'struct device' hanging off the pci_dev.

	Ahh, of course...  Perfection...the enemy of progress...
