Log:
  kgdb: initialize n_type field of nlist entry for kvm_nlist call
  
  kvm_nlist skips lookup for entries that have n_type != N_UNDF.
  N_UNDF happens to be zero, so n_type typically has a correct
  value by accident, but not always.
  Note: jhb has a patch that replaces kvm_nlist use with direct
  gdb parsing.
  
  MFC after:	5 days
  X-MFC-Note:	unless jhb commits kvm_nlist => kgdb_parse change
