Stack switching for interrupt handlers happens in C now for both 64 and
32bit. Remove the stale comment which claims the contrary.

* to the function as error_code argument which needs to be truncated

- * On 64-bit idtentry_enter/exit() are invoked in the ASM entry code before
- * and after switching to the interrupt stack. On 32-bit this happens in C.
- *
* irq_enter/exit_rcu() are invoked before the function body and the
- * KVM L1D flush request is set.
