Make sure that debugfs entry works as expected by reading
back the sequence number that was written.

For seqno comparison to work they have to be less than UINT32_MAX/2
apart. So when crossing the half way of seqno space, be careful not
to sync anything as this causes gpu hangs. Do real test with
syncing only when we are about to wrap.
v2: Don't spam if no rendercopy was found, only warn once
This test uses debugfs entry to set next_seqno close
to a wrapping point and then creates a load with dependant
buffer objects or with specified command to induce the wrap.
v2: Use new get_rendercpy_func as suggested by Daniel Vetter.
