vp10: clip MVs before adding to find_ref_mvs() list.
This causes the output of find_ref_mvs() to always be unique or zero. A nice side-effect of this is that it also causes the output of find_ref_mvs_sub8x8() to be unique-or-zero, and it will not ignore available candidate MVs under certain conditions. See issue 1012.
