Fix for abi_x86_interrupt for newest nightly 1.90

[rsahwe]

#553

This fix just removes all of the diverging. This would be a breaking change and might cause undesired behavior.

Alternatively the idt could maybe use wrapper functions so that the handler functions don't have the x86_interrupt abi.

Hi @rsahwe, thank you for your contribution!

As you noticed, rustc no longer accepts -> ! as the return type for "x86-interrupt". This is a regression in rustc. There is ongoing work to fix this. Given this, we hope that once this is eventually fixed in rustc, we won't need to make any changes to this crate.

If we make a breaking change now, we'll likely have to do another breaking change to revert that once the rustc fix lands, so I think we should wait for now.

Until then, you'll have to pin your nightly version or disable the abi_x86_interrupt feature. I recognize that this is not ideal.
