packet-smb2: correctly dissect SMB2 TRANSFORM_HEADER Flags
In the SMB 3.1.1 dialect, this field is interpreted as the Flags field, which indicates how the SMB2 message was transformed:
Encrypted 0x0001
- The message is encrypted using the cipher that was negotiated for this connection.
In the SMB 3.0 and SMB 3.0.2 dialects, this field is interpreted as the EncryptionAlgorithm field,
which contains the algorithm used for encrypting the SMB2 message. This field MUST be set to one of the following values:
SMB2_ENCRYPTION_AES128_CCM 0x0001
- The message is encrypted using the AES128 CCM algorithm.
For dissection it's enough to expect SMB 3.1.1, as the value and the meaning
of 0x0001 is always the same (as AES128 CCM was the only possible algorithm before 3.1.1)
