debug: Avoid setting BUGFLAG_WARNING twice
Dan reported that his static checking complains about BUGFLAG_WARNING being set on both sides of the bitwise-or, it figures that that might've been an unintentional mistake. Since there are no architectures that implement __WARN_TAINT() (I converted them all to implement __WARN_FLAGS()), and all __WARN_FLAGS() implementations already set BUGFLAG_WARNING, we can remove the bit from BUGFLAG_TAINT() and make Dan's checker happy.
