[PATCH 5/5] staging: hv: fix a kernel warning in netvsc_linkstatus_callback()

[Haiyang Zhang <haiyangz@microsoft.com>]

netif_notify_peers() is not allowed in netvsc_linkstatus_callback() on some
distros, because netvsc_linkstatus_callback() is within IRQ context. So we
move the first call to netif_notify_peers() into queued work as well, but with
zero delay.

This should also be back-ported to stable kernels 2.6.32 and later.
