msm: mdss: fix pipe cleanup for multi-rect pipes

Browse source 
For multi-rect pipes, driver tries to release the
pipe only when both pipes for both rectangles
are in the destroy list. Current code always
detects that there are two pipes with the same
number in the list, since the first iteration to
look for the pipe in the list always correspond to
the same pipe used as the initial index.
This causes that driver unnecesary halt the dma pipe
when still in use for the second rect that is still not
freed. Fix this issue by making sure the same pipe
objects are not used to check if there are two pipes
with the same index in the release list.
