msm: mdss: fix compression ratio for logic for rotator and wfd

Currently rotator driver is using input compression ratio for output.
This is not correct because it is possible to have different input and
output formats which changes compression ratios. Similarly for WFD, use
output compression ratio passed by user-space.
