cpuset(9): Refer to CPU_SETSIZE not MAXCPU
The maximum CPU number of a cpuset_t is determined by CPU_SETSIZE. In
the kernel this is MAXCPU, but in userspace it is CPU_MAXSIZE unless
CPU_SETSIZE is defined before including sys/_cpuset.h. CPU_MAXSIZE is
256 and in userspace MAXCPU is generally 1 because it being set to a
larger MD value is gated on SMP being defined (not generally the case in
userspace).
