/** Shut down the PSA Crypto subsystem, allowing persistent keys to survive.
* Expect a clean shutdown, with no slots in use.
* mbedtls_psa_random_free() is called before any check for remaining open
* keys because when AES_C is not defined, CTR_DRBG relies on PSA to perform
* AES-ECB so it holds an open AES key for that since psa_crypto_init().
*
* If some key slots are still in use, record the test case as failed and
* jump to the `exit` label.
