PCI/MSI: Kill redundant call of irq_set_msi_desc() for MSI-X interrupts

It is the repsonsibility of arch_setup_msi_irq()/arch_setup_msi_irqs()
to call irq_set_msi_desc() to associate IRQ descriptors and MSI
descriptors. Kill the redundant call of irq_set_msi_desc() for MSI-X
interrupts in the PCI MSI core.
