[Qemu-devel] [PULL 23/40] qapi: Remove obsolete tests for MAX collision

[Markus Armbruster <armbru@redhat.com>]

From: Eric Blake <eblake@redhat.com>

Now that we no longer collide with an implicit _MAX enum member,
we no longer need to reject it in the ad hoc parser, and can
remove several tests that are no longer needed.
