drm/amd/display: Properly reuse completion structure
commit 0cf8307adbc6beb5ff3b8a76afedc6e4e0b536a9 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.
