[PATCH 15/19] qapi: Fold normalize_features() into check_features()

[Markus Armbruster <armbru@redhat.com>]

check_features() is always called together with normalize_features():
the former in check_struct() and check_command(), the latter in their
caller check_exprs().  Fold the latter into the former.
