ctrl: on parse errors, return a detailed message to sender

The recently added ctrl_cmd_parse2() returns non-NULL cmd with error messages
upon parsing errors. In handle_control_read(), use ctrl_cmd_parse2() and send
those back to the CTRL command sender as reply.

Retain the previous "Command parser error" reply only in case ctrl_cmd_parse2()
should return NULL, which shouldn't actually happen at all.
