disp: msm: sde: disable solver for autorefresh disable transition

RSC Solver enable during autorefresh enable need to be avoided.
Currently in SDE driver, solver is disabled if autorefresh is
enabled from HLOS client but autorefresh disable transition is not
considered. This change avoids RSC solver mode in autorefresh
disable transition commit including splash hand-off.
