Fix selector of protocol for LSA RPC binding string
For Windows Server 2012R2 and others which force SMB2 protocol use we have to specify right DCE RPC binding options. For using SMB1 protocol we have to omit specifying SMB2 protocol and anything else or otherwise SMB1 would be considered a pipe to connect to. This is by design of a binding string format.
