6.15-stable review patch. If anyone has any objections, please let me know.

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.
