qapi: Fix error message format regression
Commit 52a474180ae3 changed reporting of errors connected to a source
location without mentioning it in the commit message. For instance,
$ python scripts/qapi-gen.py tests/qapi-schema/unknown-escape.json
tests/qapi-schema/unknown-escape.json:3:21: unknown escape \x
became
scripts/qapi-gen.py: tests/qapi-schema/unknown-escape.json:3:21: unknown escape \x
This is not how compilers report such errors, and Emacs doesn't
recognize the format. Revert this change.
Fixes: 52a474180ae3 (qapi-gen: Separate arg-parsing from generation)
