net: Add napi_struct parameter irq_suspend_timeout

Browse Source 
Add a per-NAPI IRQ suspension parameter, which can be get/set with
netdev-genl.

This patch doesn't change any behavior but prepares the code for other
changes in the following commits which use irq_suspend_timeout as a
timeout for IRQ suspension.
