Use use_prev_frame_mvs flag for ref mv search branch
Use use_prev_frame_mvs flag for ref mv search branch

Replace error_resilient flag with use_prev_frame_mvs in
vp9_pick_inter_mode reference motion vector search selection.
This effectively turns off the simplified ref mv search in the
settings of frame resizing, even if error-resilient mode is off.
