msm: mdss: fix layer skipping due to dirty pipe

Browse source 
Pipe is marked dirty if it was newly allocated during validate. This
prevents unintentional staging for dirty pipes to HW. However when
the same pipe is used again with good configuration, dirty flag should
be reset. This is missing and leads to skipping of certain layers and
flooding of error logs. Fix this by resting dirty flag when pipe is
successfully validated.
