Do not send SMB2 signatures for SMB3 frames
Restructure code to make SMB2 vs. SMB3 signing a protocol
specific op. SMB3 signing (AES_CMAC) is not enabled yet,
but this restructuring at least makes sure we don't send
an smb2 signature on an smb3 signed connection. A followon
patch will add AES_CMAC and enable smb3 signing.
