Ming Lei e58114824f scsi: megaraid_sas: fix selection of reply queue 
commit adbe552349 upstream.

Since commit 84676c1f21 ("genirq/affinity: assign vectors to all
possible CPUs") we could end up with an MSI-X vector that did not have
any online CPUs mapped. This would lead to I/O hangs since there was no
CPU to receive the completion.

Retrieve IRQ affinity information using pci_irq_get_affinity() and use
this mapping to choose a reply queue.
