When doing calls to syscall_authenc_xyz functions (all of them except
syscall_authenc_init) there is no check being done that the state coming
from the TA has been initialized to a valid authenticated encryption
state. As a consequence of that it's possible to redirect execution to
other functions. Doing like that will make TEE core end up with a data
abort.
