hv_netvsc: minor fixes

These are improvements to netvsc driver. They aren't functionality
changes so not targeting net-next; and they are not show stopper
bugs that need to go to stable either.

v2
   - drop the irq flags patch, defer it to net-next
   - split the multicast filter flag patch out
   - change propogate rx mode patch to handle startup of vf

Of these patches in the set is very important for fixing UDP performance
on SRIOV after Meltdown:

hv_netvsc: defer queue selection to VF
When VF is used for accelerated networking it will likely have
more queues (and different policy) than the synthetic NIC.
This patch defers the queue policy to the VF so that all the
queues can be used. This impacts workloads like local generate UDP.
