ffmpeg | branch: master | Niklas Haas <git at haasn.dev> | Wed Dec 11 10:13:46 2024 +0100| [fe9bf7cd5235bbdbe95eb610540e6e8851e58b7d] | committer: Niklas Haas

checkasm/sw_scale: add assertion for hscale assumption

This code only checks hcScale. In practice this is not an issue because
the function pointers should always be identical to hyScale for the same
filter size.

Add an assertion just to make sure this assumption never regresses.
