[PATCH 4/5] scsi: lpfc: fix lpfc_nvmet_setup_io_context() if no further cpus set

After commit 596ff4a09b89 ("cpumask: re-introduce constant-sized cpumask
optimizations"), when NR_CPUS <= BITS_PER_LONG, small_cpumask_bits used
a macro instead of variable-sized for efficient.
If no further cpus set, the cpumask_next() returns small_cpumask_bits,
it must greater than or equal to nr_cpumask_bits, so fix it to correctly.
