Subject: [PATCH v18 01/10] idr: add #include <linux/bug.h>

The <linux/bug.h> was removed from radix-tree.h by the following commit:
f5bba9d11a256ad2a1c2f8e7fc6aabe6416b7890.

Since that commit, tools/testing/radix-tree/ couldn't pass compilation
due to: tools/testing/radix-tree/idr.c:17: undefined reference to
WARN_ON_ONCE. This patch adds the bug.h header to idr.h to solve the
issue.
