drm/msm/sde: abort inline rotation on rot commit error

Inline rotation commits require both the DRM/KMS and rotator
drivers to accept their respective configurations to proceed.
Commits with inline rotation need to fail gracefully in the
event the rotator driver flags an error during the commit
phase, so trigger a fallback 'is error' kickoff within the
encoder during those situations.
