[Qemu-devel] [PATCH] qdev-monitor-test: simplify using g_assert_cmpstr()

[Stefan Hajnoczi <stefanha@redhat.com>]

Use g_assert_cmpstr() instead of combining g_assert() and strcmp(3).
This simplifies the code since we no longer have to play games to
distinguish NULL from "" using "(null)".

gcc extension haters will also be happy that ?: was dropped.
