The threadirqs kernel parameter can be used to force threaded IRQs even
on non-PREEMPT_RT kernels. Use force_irqthreads to determine if we can
skip disabling local interrupts. This defaults to false on regular
kernels, and is always true on PREEMPT_RT kernels.

Is this fixing a behaviour or is this from the clean up/ make it pretty
category?

It's in response to [1].

[1] https://lore.kernel.org/netdev/20240912084322.148d7fb2@kernel.org/ (local)

The forced-threaded interrupts run with disabled interrupts on !RT so
this change should not fix anything.

OK, so maybe this isn't necessary at all?
