smb: fix secondary channel creation issue with kerberos by populating hostname when adding channels

Browse Source 
commit 306cb65bb0cb243389fcbd0a66907d5bdea07d1e upstream.

When mounting a share with kerberos authentication with multichannel
support, share mounts correctly, but fails to create secondary
channels. This occurs because the hostname is not populated when
adding the channels. The hostname is necessary for the userspace
cifs.upcall program to retrieve the required credentials and pass
it back to kernel, without hostname secondary channels fails
establish.
