linuxkm/linuxkm_wc_port.h:

* fix WC_LINUXKM_ROUND_UP_P_OF_2() to not round up values that are already powers of 2, nor values larger than 8192.

linuxkm/lkcapi_glue.c:
* fix gating on km_AesSetKeyCommon().
* small stack refactors of Aes objects in self-test routines.
* change kmalloc/free to malloc/free in self-test routines.
* fix error-path "return"s to "goto exit"s in self-test routines.
* fix memory leak around large_input in aes_xts_128_test().

wolfcrypt/benchmark/benchmark.c:
* smallstack refactors in bench_chacha() and bench_chacha20_poly1305_aead().
* add error handling in bench_chacha().

wolfcrypt/src/chacha20_poly1305.c: smallstack refactor for wc_ChaCha20Poly1305_Encrypt() and wc_ChaCha20Poly1305_Decrypt().
