[Intel-gfx] [PATCH] drm/i915/psr2: Do full fetches when doing async flips

[José Roberto de Souza]

Async flips are not supported by selective fetch and we had a check
for that but that check was only executed when doing modesets.
So moving this check to the page flip path, so it can be properly
handled.

This fix a failure in kms_async_flips at test-cursor.
