some problems about AES CCM

[LeeRJ]

1st problem:

There are some failed case when i run  \v2.9.1\modules\bsim_hw_models\nrf_hw_models\tests\zephyr_apps\54_aar_ccm_ecb\src\test_ccm.c

2nd problem:

If I reduce the amount of encrypted data in test_ccm_12b_encr_ble_255b_w_adata_nomac, the encryption process gets stuck.

	for (uint8_t len = 0; len <= 255; len++)

I wrote an example of encrypting data of different lengths according to test_ccm_12b, but it got stuck when len=36.
