dahdi: Remove unused functions __buf_munge and __buf_cpush.

Browse Source 
These functions were only defined if BUF_MUNGE was defined, but even if
that symbol is defined there is not anyplace in the driver where these
functions were then called.  This has been in the code since rev 87 so
this is most likely stale debugging code.

Feel free to revert if this is actually used somewhere that is not
apparent.

Here is where the functions were originally added to the drivers:
