Subject: Set a default mv entropy if no tokens are coded.
X-Git-Tag: v1.3.0~1217^2~296^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=319dd1c0f58d3db46713460ca10e920f2b18b605;p=libvpx

Set a default mv entropy if no tokens are coded.

This doesn't affect the result, since there are no MVs coded using this
entropy. It does, however, silence valgrind warnings about uninitialized
variables.
