scsi: arcmsr: Use pci_alloc_irq_vectors
Switch the arcmsr driver to use pci_alloc_irq_vectors. We need to two calls to pci_alloc_irq_vectors as arcmsr only supports multiple MSI-X vectors, but not multiple MSI vectors. Otherwise this cleans up a lot of cruft and allows to use a common request_irq loop for irq types, which happens to only iterate over a single line in the non MSI-X case.
