scsi: mpt3sas: fix an out of bound write
cpu_msix_table is allocated to store online cpus, but pci_irq_get_affinity
may return cpu_possible_mask which is then used to access cpu_msix_table.
That causes bad user experience. Fix limits access to only online cpus,
I've also added an additional test to protect from an unlikely change in
cpu_online_mask.
