3c52x: remove IRQF_SAMPLE_RANDOM from legacy MCA drivers.

If you are genuinely using one of these legacy MCA drivers
then you are tragically on hardware where you really don't
have the extra CPU cycles to be wasting on this.

In addition, it makes two less cases for people to inadvertently
blindly copy flags from without explicitly thinking whether it
makes sense -- see the addition to feature-removal.txt as per
commit 9d9b8fb0e5ebf4b0398e579f6061d4451fea3242.
