disp: msm: sde: silence ppb horizontal width check

PPB size programming checks for the max horizontal width of the
panel by checking all available modes. In some DP usecases,
it is possible that this information is not ready at this point.
However, this is not an error, as by default driver will set the
maximum size.

This change reduces the error log to a debug warning.
