This patch allow auot completion work normal in sub command case,
"info block [DEVICE]" can auto complete now, by re-enter the completion
function. Also, original "info" is treated as a special case, now it is
treated as a sub command group, global variable info_cmds is not used
any more.
"help" command is still treated as a special case, since it is not a sub
command group but want to auto complete command in root command table.
