cifs: remove unused SMB2 config and mount options

There's no SMB2 support in the CIFS filesystem driver, so there's no need to
have a config and mount option for it.

-         This enables experimental support for the SMB2 (Server Message Block
-         version 2) protocol. The SMB2 protocol is the successor to the
-         popular CIFS and SMB network file sharing protocols. SMB2 is the
-         native file sharing mechanism for recent versions of Windows
-         operating systems (since Vista).  SMB2 enablement will eventually
-         allow users better performance, security and features, than would be
-         possible with cifs. Note that smb2 mount options also are simpler
-         (compared to cifs) due to protocol improvements.
