w1: Silence ds1wm warnings related to mfd_get_cell changes
mfd_get_cell returns a const, so change the ds1wm client to store a const mfd cell. This silences type mismatch warnings. Since we're guaranteed to have the mfd_cell, we can also simplify the code a bit to get rid of a temporary variable and NULL check.
