msm: kgsl: Always set the active powerlevel when changing clock rates

kgsl_pwrctrl_pwrlevel_change might be called when clocks are on or off.
If clocks are off we don't step the clock rate and the active_pwrlevel
won't be set to the new and correct level.  Set active_pwrlevel to its
new level before doing anything else.
