Fix crash when encoding using libschroedinger.

Currently only pixel and half-pixel motion vector precisions are supported in
libschroedinger. Setting the mv_precision field to 2 (i.e. quarter pixel)
causes a crash in the libschroedinger encoder calls. By not setting this
parameter, we fall back to the default value used in libschroedinger.
