qapi/parser: Mollify mypy

re.match(r'^ *', ...) can't fail, but mypy doesn't know that and
complains:

    scripts/qapi/parser.py:444: error: Item "None" of "Match[str] | None" has no attribute "end"  [union-attr]

Work around by using must_match() instead.

Fixes: 8107ba47fd78 (qapi: Add documentation format validation)
