msm: mdss: Avoid unnecessary warnings during pipe unstaging

Browse source 
In some cases, when the pipe is being unstaged from right mixer,
some unnecessary processing is done and warning messages are
being printed. This can be avoided by updating the right stage
information after unstaging the pipe.
