[AMDGPU] Remove getBidirectionalReasonRank

This method inverts the Reason field of a scheduling candidate. It does right comparison between RegCritical and RegExcess, but everything else is broken. In fact it can prefer less strong reason such as Weak over RegCritical because Weak > -RegCritical.

The CandReason enum is properly sorted, so just remove artificial ranking.

Presumably, it's a scheduling issue. The commit looks correct though.
