cardem: fix USB message parsing

the msg->l2h pointer was not set but used later on, e.g. in
dispatch_usb_command_cardem, case SIMTRACE_MSGT_DT_CEMU_SET_ATR):
>   case SIMTRACE_MSGT_DT_CEMU_SET_ATR:

>   >   card_emu_set_atr(ci->ch, atr->atr, atr->atr_len);
l2h is by default 0, thus not pointing to the actual message l2h.
I wonder how cardem worked worked before with this issue though.
