disp: msm: dsi:Handle pm_runtime_put_sync return value properly



Currently,power resource disable fails when pm_runtime_put_sync
returns negative values. Due to this, clock state update is
failing. pm_runtime_put_sync can return negative values in
scenarios where  pending resume requests take precedence over
suspends. This change allows pm_runtime_put_sync to return
negative vales also.
