cryptodev: check if symmetric sessions are supported

Browse Source 
Since asymmetric functionality will be implemented soon,
not all PMDs must support symmetric sessions.
Therefore, a check is added if a device does not implement
the symmetric functions, meaning that the device does not
support symmetric operations.
