Do not attempt to do cifs operations reading symlinks with SMB2
When use of symlinks is enabled (mounting with mfsymlinks option) to non-Samba servers, we always tried to use cifs, even when we were mounted with SMB2 or SMB3, which causes the server to drop the network connection. This patch separates out the protocol specific operations for cifs from the code which recognizes symlinks, and fixes the problem where with SMB2 mounts we attempt cifs operations to open and read symlinks. The next patch will add support for SMB2 for opening and reading symlinks. Additional followon patches will address the similar problem creating symlinks.
