msm: mdss: exclude cursor from dirty pipe logic

Browse source 
Pipes are marked dirty when the userspace and kernel pipe management
are out of sync and the kernel stabilizes itself with the next prepare
call. The prepare call would not involve cursor pipes, as they are
handled separately through the cursor ioctl. This leaves the cursor
pipe to stay dirty and fails the following pre_commit. Fix to avoid
setting cursor pipe as dirty.
