isdn: fix section mismatch warnings

Fix the following section mismatch warnings:

WARNING: drivers/isdn/hardware/eicon/divadidd.o(.init.text+0xc4): Section mismatch: reference to .exit.text: (between 'init_module' and 'diddfunc_init')
WARNING: drivers/isdn/hardware/eicon/divas.o(.init.text+0xf4): Section mismatch: reference to .exit.text:divasfunc_exit (between 'init_module' and 'divasfunc_init')
WARNING: drivers/isdn/hardware/eicon/divas.o(.init.text+0x10d): Section mismatch: reference to .exit.text:divasfunc_exit (between 'init_module' and 'divasfunc_init')
WARNING: drivers/isdn/hardware/eicon/divas.o(.init.text+0x148): Section mismatch: reference to .exit.text:divasfunc_exit (between 'init_module' and 'divasfunc_init')

They all point to situation whare a function marked __init calls a function
marked __exit - but the __exit section may have been discarded.

Note: This warning is generated by a modified copy of modpost in my
      tree. It will soon hit upstearm.
