scsi: ipr: Use pci_irq_allocate_vectors
Switch the ipr driver to use pci_alloc_irq_vectors. We need to two
calls to pci_alloc_irq_vectors as ipr 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.
