UPSTREAM: cpumask: make cpumask_next_wrap available without smp
The kbuild robot shows build failure on machines without CONFIG_SMP:
drivers/net/virtio_net.c:1916:10: error:
implicit declaration of function 'cpumask_next_wrap'
cpumask_next_wrap is exported from lib/cpumask.o, which has
lib-$(CONFIG_SMP) += cpumask.o
same as other functions, also define it as static inline in the
NR_CPUS==1 branch in include/linux/cpumask.h.
If wrap is true and next == start, return nr_cpumask_bits, or 1.
Else wrap across the range of valid cpus, here [0].
