[wasm] Pass correct code section start in streaming compilation
The streaming decoder computed the code section start from the passed "offset". That offset is computed from the module offset *after* the number of functions has been read. Hence 1 is subtracted, with the comment: // The offset passed to {ProcessCodeSectionHeader} is an error offset and // not the start offset of a buffer. Therefore we need the -1 here. That subtraction of 1 worked when the number of functions was encoded in a 1-byte LEB, otherwise it was off. This CL fixes the immediate issue of passing the right code offset. The usage of the previously existing offset also seems wrong, and I will try to clean that up in a follow-up CL.
