Summary

A user reported kvm_nlist(3) leaks memory. I found there are two leaks. First, it had to free(3) dpcpu_off (introduced in rS204494) from kvm_close(3). Second, it is not free()'ing temporary buffer introduced in D3341 (rS291406). Also, an unchecked calloc(3) failure was fixed while I am in the neighborhood.
