cifs: fix composing of mount options for DFS referrals
With the change to ignore the unc= and prefixpath= mount options, there is no longer any need to add them to the options string when mounting. By the same token, we now need to build a device name that includes the prefixpath when mounting. To make things neater, the delimiters on the devicename are changed to '/' since that's preferred when mounting anyway. v2: fix some comments and don't bother looking at whether there is a prepath in the ref->node_name when deciding whether to pass a prepath to cifs_build_devname. v3: rebase on top of potential buffer overrun fix for stable Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
