Finally now that edge interrupts are properly identified, we can enable
CONFIG_HARDIRQS_SW_RESEND which will make the core re-send them if
they occur while masked, which some drivers rely upon.

This fixes issues with lost interrupts on some Mellanox adapters.

Broken since forever?

Cc stable?

Broken since forever but I want a bit more testing before that goes to
stable. Some drivers like Mellanox had a workaround but they want to
remove it.

OK.

I've put it in fixes-test (should end up in fixes), and added it to my
"probably for stable" list:
