PCI/MSI: Check for NULL affinity mask in pci_irq_get_affinity()
If msi_setup_entry() fails to allocate an affinity mask, it logs a message
but continues on and allocates an MSI entry with entry->affinity == NULL.
Check for this case in pci_irq_get_affinity() so we don't try to
dereference a NULL pointer.
