Aux transfers always fail with non-zero status flags when there's
nothing connected on the port, so we don't usually need to see all of
the debugging information from it. Also, we try reprobing a -lot-, so
without ratelimiting most of the kernel log is filled up with messages
from radeon_dp_aux_transfer_native.
