Log:
dahdi: Move WARN_ON_ONCE from wctc4xxp driver to include/dahdi/kernel.h

I only generally test on RHEL 4 when testing against kernels older
than 2.6.18. Apparently OpenSUSE 10.1 runs with 2.6.16 and doesn't
have WARN_ON_ONCE backported. I took the patch Richard Miller
originally attached to the issue and moved it to
include/dahdi/kernel.h so it would be available for all the board
drivers in the future.
