KASAN: Disable checking before triggering a panic
KASAN hooks will not generate reports if panicstr != NULL, but then
there is a window after the initial panic() call where another report
may be raised. This can happen if a false positive occurs; to simplify
debugging of such problems, avoid recursing.
