drm/amd/display: Correct updating logic of dcn21's pipe VM flags

Browse source

[Why]:
Renoir's pipe VM flags are not correctly updated if pipe strategy has
changed during some scenarios. It will result in watermarks mistakenly
calculation, thus underflow and garbage appear.

[How]:
Correctly update pipe VM flags to pipes which have been populated.
