Stylon Wang 118ad80d27 drm/amd/display: Properly reuse completion structure
commit 0cf8307adb upstream.

[Why]
Connecting displays to TBT3 docks often produces invalid
replies for DPIA AUX requests. It turns out the completion
structure was not re-initialized before reusing it, resulting
in immature wake up to completion.

[How]
Properly call reinit_completion() on reused completion structure.
