Simplify the code and eliminate per-encryption-op dynamic memory allocations by switching from crypto_skcipher to crypto_sync_skcipher, and from dynamic request allocation to SYNC_SKCIPHER_REQUEST_ON_STACK.
Previously, this change would have made the x86 accelerated AES code no longer be used, which would have been very bad. However, I fixed that in 6.16. So we can make this simplification now. This patchset applies to fscrypt/for-next. The base-commit (listed below) can be found in next-20250708 Changed in v2: - Added patches that remove the gfp_t argument from functions that no longer need it. - Eliminated the goto in derive_key_aes(). - Improved commit messages.
