When source split is used, pipe can be staged on two mixers or it can
be staged on right blend of a mixer. It is also possible that same pipe
is used at different z_order in consecutive frames. When pipe's z_order
is changed and it goes from two mixers to single mixer or right blend to
left blend or any other such variations, pipe needs to un-stage properly.
Fix issues in current code by correcting order of state assignments.

mixer set roi which sets valid_roi flag. However with partial update
there is a requirement that for a given ctl path, roi is not valid

msm: mdss: enable source split with dual-dsi partial update, valid_roi
check was added when doing mixer setup to prevent incorrect HW
configurations. However valid_roi is not set for a ctl path for rotator.
Because of this params_changed value for rotator mixer is not getting
reset which leads to data overflow for variable params_changed. This
overflow prevents prepare_rotation function to be called which in turn
leads to data mismatch errors. Fix this issue by moving valid_roi check
after rotator is serviced during mixer setup.
