ffmpeg | branch: master | Zhao Zhili <zhilizhao at tencent.com> | Sat Sep 17 12:30:01 2022 +0800| [686096739b129c7e3ea26be29c875e0887e58c49] | committer: Zhao Zhili

fftools/ffmpeg_filter: configure min_hard_comp unconditionally

There are two issues here. Firstly, the floating-point comparison
is always true. Seconly, the code depends on the default value of
min_hard_comp implicitly, which can be dangerous.

Partially fixes ticket 9859.
