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:
