[Yakkety][PULL] CIFS: Enable encryption for SMB3

[Joseph Salisbury]

There has been work upstream to enable encryption support for SMB3
connections. This is a particularly valuable (and commonly requested)
feature with the Azure Files service as encryption is required to connect
to an Azure Files storage share from on-prem or from a different Azure region.
