The expression `VBAN_PROTOCOL_SERIAL | vban_BPSList[14]` is assigned
to an 8 bit field of the header, but, `vban_BPSList[14]` being
115200, it does not fit. Instead, its index, 14, should be
placed in the header.
In addition to fixing the issue, add `-Werror=constant-conversion`,
and clang diagnostic that catches such issues.
Fixes: 1a5514e5cf ("module-vban: create streams per stream_name")
