selftests: make order checking verbose in msg_zerocopy selftest
[ Upstream commit 7d6d8f0c8b700c9493f2839abccb6d29028b4219 ]
We find that when lock debugging is on, notifications may not come in
order. Thus, we have order checking outputs managed by cfg_verbose, to
avoid too many outputs in this case.
