Log message:
Add missing bus_space_barrier() in mcx_cmdq_post() - without this, cmdq
operations during attach fail on some amd64 systems using the TSC delay
function, seemingly as there aren't enough memory operations happening to
get the doorbell write out to the device otherwise. The lapic delay
function didn't expose this problem.
