scsi: lpfc: Break out of IRQ affinity assignment when mask reaches nr_cpu_ids

The purpose of the lpfc_next_online_cpu() call is to save the CPU index for
the next iteration of the for (index = 0; index < vectors; index++) loop.
Because we’ve reached the last iteration of the loop, cpumask_next(cpu,
aff_mask) returns nr_cpu_ids.  Thus, if we already know we've reached the
last iteration of the IRQ affinity assignment loop, then we can just break
and exit.
