Fixes #8848.

Motivation / Problem

Can't buy train engine when the "Engines only" filter is active.

Description

The CargoID passing across the commands in the end have to be smaller than the number of cargoes or be the invalid cargo. So changes the CargoID to CT_INVALID.

if (cargo >= NUM_CARGO && cargo != CT_INVALID) return CMD_ERROR;

Limitations

None.
