rtw88: leave PS state for dynamic mechanism

Browse Source 
Dynamic mechanism requires BB/RF working to adjust
hardware settings. But PS state periodically turns
off BB/RF, could lead to wrong setting.

So leave PS state before DM to make sure it works.
And then check if we can enter PS state again.
