Assertion failuer in cryptodev_builtin_close_session()
Description of problem:
In the function _cryptodev_builtin_close_session(),_ an assertation happened:

```
qemu-fuzz-x86_64: qemu/backends/cryptodev-builtin.c:430: int cryptodev_builtin_close_session(CryptoDevBackend *, uint64_t, uint32_t, CryptoDevCompletionFunc, void *): Assertion `session_id < MAX_NUM_SESSIONS && builtin->sessions[session_id]' failed.
