[PATCH 02/15] cifs: add tcon field to cifsFileInfo struct

[Jeff Layton <jlayton@redhat.com>]

Eventually, we'll have more than one tcon per superblock. At that point,
we'll need to know which one is associated with a particular fid. For
now, this is just set from the cifs_sb->tcon pointer, but eventually
the caller of cifs_new_fileinfo will pass a tcon pointer in.
