[CIFS] Endian convert UniqueId when reporting inode numbers from server files

Jeff made a good point that we should endian convert the UniqueId when we use
it to set i_ino Even though this value is opaque to the client, when comparing
the inode numbers of the same server file from two different clients (one
big endian, one little endian) or when we compare a big endian client's view
of i_ino with what the server thinks - we should get the same value
