msm: mdss: fix pp setup on SSPP pipe in rotation scenario
mfd is not updated on controller when pipe is setup
for rotation scenario. However, post processing module
check it for all use cases that leads to pp update
failure SSPP pipe. This change avoids the extra checking
and allows pp module to update SSPP pipe in all use
case scenarios.
