preempt: Remove hardirq_disable_count()

Browse source

It turns out the previous usage of hardirq_disable_count() in
__irq_exit_rcu() would cause softirq pending issues. Without that usage,
hardirq_disable_count() doesn't need to exist, so remove it.

Also move hardirq_disable_enter/exit() into the Rust specific interrupt_rc
header.
