Fix a bug in frame scaling

This change fixed a corner case bug reealed by b/311394513.
During the frame scaling, vpx_highbd_convolve8() and vpx_scaled_2d()
requires both x_step_q4 and y_step_q4 are less than or equal to a

frame_nonnormative() that supports arbitrary scaling.

nonrd_pickmode=0/off is the only feature in realtime mode that

Currently allocations are done at encoder creation time. Going from
threaded to non-threaded would cause a crash.
