drivers/isdn: Adjust confusing if indentation

In hisax/hfc_sx.c and mISDN/l1oip_core.c, the code after the if is
outdented so that it is not aligned with the if branch.

In mISDN/dsp_cmx.c, an else is added between the original if branch and the
following statement, in line with the code following it.  Without this
change, the first assignment to dsp->rx_W has no useful effect.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r disable braces4@
position p1,p2;
statement S1,S2;
@@

(
if (...) { ... }
|
if (...) S1@p1 S2@p2
)

@script:python@
p1 << r.p1;
p2 << r.p2;
@@

if (p1[0].column == p2[0].column):
  cocci.print_main("branch",p1)
  cocci.print_secs("after",p2)
// </smpl>
