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

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.

Why? The arguments were nicely aligned.

Because the last line went beyond 80 chars, and triggered checkpatch warning.

This is the only patch in the series that would apply (well, I didn't
try the 5/5 patch for the reasons stated there.)

Please redo these against the latest staging-next branch if you want
them applied.
