The free_cmds() function was only called on "queued_nr" if we had a "flush" command. As the "without flush for blob info" test added in the same commit shows we can't rely on that, so let's call free_cmds() again at the end. Since "nr" follows the usual pattern of being set to 0 if we've free()'d the memory already it's OK to call it twice, even in cases where we are doing a "flush".
