genirq: Remove desc->status when GENERIC_HARDIRQS_NO_COMPAT=y
If everything uses the right accessors, then enabling
GENERIC_HARDIRQS_NO_COMPAT should just work. If not it will tell you.
Don't be lazy and use the trick which I use in the core code!
git grep status_use_accessors
will unearth it in a split second. Offenders are tracked down and not
slapped with stinking trouts. This time we use frozen shark for a
better educational value.
