Subject: [PATCH] fix #3609: cifs: add support to SMB 3.11

Added support for the SMB version SMB3_11 When the `min protocol =
SMB3_11` in the smb.conf, the CIFS mount will return with the
following error:
```
CIFS VFS: cifs_mount failed w/return code = -95
```
added an optional option to use the `vers=3.11`
