- Use readonly object as lock
Info from stackoverflow:
If I want to be sure that it will be locked for all threads inside my
application:
The lock object has to be static, if it locks access to static state.
Otherwise it has to be instance, because there's no need to lock state of
one class instance, and prevent other threads to work with another class
instance at the same time.
everyone says that the object has to be "readonly" I didn't found the
reason
Well, it doesn't have to be. This is just a best practice, which helps you
to avoid errors.

- Drop redundant code.
I should read code carefully, mbed TLS will set operation
when invoking mbedtls_cipher_setkey(), the last param
const mbedtls_operation_t operation is what we want.
