CVE-2025-39924

In the Linux kernel, the following vulnerability has been resolved: erofs: fix invalid algorithm for encoded extents The current algorithm sanity checks do not properly apply to new encoded extents. Unify the algorithm check with Z_EROFS_COMPRESSION(_RUNTIME)_MAX and ensure consistency with sbi->available_compr_algs.
