scsi: qla2xxx: Fix qla2x00_request_irqs() for MSI
commit 45dc8f2d9c94ed74a5e31e63e9136a19a7e16081 upstream.
Commit 4fa183455988 ("scsi: qla2xxx: Utilize pci_alloc_irq_vectors/
pci_free_irq_vectors calls.") use pci_alloc_irq_vectors() to replace
pci_enable_msi() but it didn't handle the return value correctly. This bug
make qla2x00 always fail to setup MSI if MSI-X fail, so fix it.
BTW, improve the log message of return value in qla2x00_request_irqs() to
avoid confusion.
Fixes: 4fa183455988 ("scsi: qla2xxx: Utilize pci_alloc_irq_vectors/pci_free_irq_vectors calls.")
