fix(axfs): update rsext4 to fix journal playback data inconsistency (arceos-hypervisor#367)

* fix(axfs): update rsext4 to fix journal playback data inconsistency

The previous rsext4 version (dev-251222) had a bug where mount() reads
superblock and group descriptors before journal_replay(), but never
reloads them after replay. This causes in-memory metadata to be stale,
leading to incorrect block allocation and data corruption (TEE htree
authenc_decrypt_final error 0xFFFF3071) after system restart.

Updated rsext4 to main branch which includes the fix.
