drm/amd/display: Align the returned error code with legacy DP
[Why]
For usb4 connector, AUX transaction is handled by dmub utilizing a differnt
code path comparing to legacy DP connector. If the usb4 DP connector is
disconnected, AUX access will report EBUSY and cause igt@kms_dp_aux_dev
fail.
[How]
Align the error code with the one reported by legacy DP as EIO.
