bhyve in a 13.x jail fails to boot guests with more than one vCPU because they pass too small a buffer to VM_GET_CPUS, causing the ioctl handler to return ERANGE. Handle this the same way as cpuset system calls: make sure that the result can fit in the truncated space, and relax the check on the cpuset buffer. As a side effect, fix an insufficient bounds check on "size". The signed/unsigned comparison with sizeof(cpuset_t) fails to exclude negative values, so we can end up allocating impossibly large amounts of memory.
