    Fix list_and_get_host scenario bug

    The scenario measure the "nova host-describe <hostname>" command
    performance, the code will describe all hosts which are listed by "nova
    host-list" command performance. but the hostname seems to must be
    compute host's name, so we only can describe compute hosts.

    NOTE: change in atomics from original patch is missed here, since atomic
          refactoring patch was not included in 0.9.0 release
