Use TCP_Server_Info::origin_fullpath instead of cifs_tcon::tree_name
when building source paths for automounts as it will be useful for
domain-based DFS referrals where the connections and referrals would
get either re-used from the cache or re-created when chasing the dfs
link.

When matching DFS superblocks we can't rely on either the server's
address or tcon's UNC name from mount(2) as the existing servers and
tcons might be connected to somewhere else. Instead, check if
superblock is dfs, and if so, match its original source pathname with
the new mount's source pathname.
For DFS connections, instead of checking server's address, match its
referral path as it could be connected to different targets.

After switching to filesystem context support, we no longer need to
handle mount options string when chasing dfs referrals. Now, we set
the new values directly into smb3_fs_context.
Start working on a separate source file to handle most dfs related
mount functions as connect.c has already became too big. The
remaining functions will be moved gradually in follow-up patches.
