include/linux/idr.h: add #include <linux/bug.h>

The <linux/bug.h> was removed from radix-tree.h by commit f5bba9d1
("include/linux/radix-tree.h: remove unneeded #include <linux/bug.h>").

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.
