tools: add WARN_ON_ONCE
Patch series "Radix tree patches for 4.10", v3.
Mostly these are improvements; the only bug fixes in here relate to
multiorder entries (which are unused in the 4.9 tree).
This patch (of 32):
The radix tree uses its own buggy WARN_ON_ONCE. Replace it with the
definition from asm-generic/bug.h
