Staging: hv: vmbus: Increase the timeout value in the vmbus driver
commit 2dfde9644fe8c4a77f9c73f95b25d6300ca23b5d upstream.
On some loaded windows hosts, we have discovered that the host may not
respond to guest requests within the specified time (one second)
as evidenced by the guest timing out. Fix this problem by increasing
the timeout to 5 seconds.
It may be useful to apply this patch to the 3.0 kernel as well.
