Cleanup: Use MIN() macro

The Linux 5.16.14 kernel's coccicheck caught this. The semantic
patch that caught it was:

./scripts/coccinelle/misc/minmax.cocci

There was a third opportunity to use `MIN()`, but that was in
`FSE_minTableLog()` in `module/zstd/lib/compress/fse_compress.c`.
Upstream zstd has yet to make this change and I did not want to change
header includes just for MIN, or do a one off, so I left it alone.
