[2.6 patch] add 4 missing returns to drivers/isdn/i4l/isdn_common.c

[Adrian Bunk]

The patch below adds 4 missing returns to drivers/isdn/i4l/isdn_common.c.
I'm not 100% sure whether other return values are possible (and I don't 
have a good knowledge of the ISDN code) but at a first glance it seems 
there are no other possible return values in these functions.

I've tested the compilation with 2.6.0-test4-mm4.
