Markus Armbruster 73c40b07c6 tests/qapi-schema: Tweak to demonstrate buggy member name check
Member name 'u' and names starting with 'has-' or 'has_' are reserved
for the generator.  check_type() enforces this, covered by tests
reserved-member-u and reserved-member-has.

These tests neglect to cover optional members, where the name starts
with '*'.  Tweak reserved-member-u to fix that.  Test
reserved-member-has still covers non-optional members.

This demonstrates the reserved member name check is broken for
optional members.  The next commit will fix it.

# Potential C member name collision
# We reject use of 'u' as a member name, to allow it for internal use in
# putting union branch members in a separate namespace from QMP members.
# This is true even for non-unions, because it is possible to convert a
# struct to flat union while remaining backwards compatible in QMP.
# TODO - we could munge the member name to 'q_u' to avoid the collision
# BUG: not rejected
