If number of interrupt vectors are more than num_online_cpus()
then pci_alloc_irq_vectors_affinity() assigns cpumask based
on num_possible_cpus() to the remaining vectors because of
this interrupts are not generating for these vectors.

This patch fixes this issue by using pci_alloc_irq_vectors()
instead of pci_alloc_irq_vectors_affinity().
