[0/2] net: Fix/prevent napi_schedule() call from bare task context

Hi,

Here is a fix to a bad context calling napi_schedule() and a lockdep
assertion to prevent from that in the future. I've tried to produce
a relevant Fixes tag but I'm not confident enough with this codebase.
This call is there for many years and yet the issue got reported only
recently, so I may be missing something in the history of this driver
or in net/usb infrastructure...

Thanks.
