4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stephen Hemminger <stephen@...workplumber.org>

[ Upstream commit 68633edaef655ce94e51088ecef5dd4e1d2f6f34 ]

Since the netvsc_channel_cb is already called in interrupt
context from vmbus, there is no need to do irqsave/restore.
