Subject: [PATCH] igb_uio: fix MSI-X IRQ assignment with new IRQ function

[ backported from upstream commit d26fc87aa26953f97e6c93d07ee9cc1415e44e20 ]

The patch which introduced the usage of pci_alloc_irq_vectors
came after the patch which switched to non-threaded ISR (f0d1896fa1),
but did not use non-threaded ISR, if pci_alloc_irq_vectors
is used.
