    sbin/mount_hammer: Fix mount(2) error handling
    
    Move mount(2) error handling code to a newly added function
    test_volumes().
    
    * Omit printing strcated volume names since this is obvious
      from an error message for each volume. Also note mount(2)
      could fail when open(2), read(2) and signature check, etc
      don't fail which makes this confusing (see 331432f3).
    * Add vol_count check in addition to signature check.
