cifs: set domainName when a domain-key is used in multiuser
[ Upstream commit f2aee329a68f5a907bcff11a109dfe17c0b41aeb ]
RHBZ: 1710429
When we use a domain-key to authenticate using multiuser we must also set
the domainnmame for the new volume as it will be used and passed to the server
in the NTLMSSP Domain-name.
