[PATCH v2 2/2] PCI/MSI: Remove the redundant irq_set_msi_desc()

[Yijing Wang]

Irq and msi_desc will be associated in arch MSI
setup code regardless of MSI or MSI-X type.
The irq_set_msi_desc() in msix_program_entries()
is redundant.

The typical MSI setup flow:
pci_enable_msix()
msix_capability_init()
arch_setup_msi_irqs()
native_setup_msi_irqs() e.g in x86
setup_msi_irq()
irq_set_msi_desc_off() <---
