xfrm: add new packet offload flag
In the next patches, the xfrm core code will be extended to support
new type of offload - packet offload. In that mode, both policy and state
should be specially configured in order to perform whole offloaded data
path.
Full offload takes care of encryption, decryption, encapsulation and
other operations with headers.
As this mode is new for XFRM policy flow, we can "start fresh" with flag
bits and release first and second bit for future use.
