Heiner Kallweit 61e6b82e7b igb: fix deadlock caused by taking RTNL in RPM resume path

[ Upstream commit ac8c58f5b535d6272324e2b8b4a0454781c9147e ]

Recent net core changes caused an issue with few Intel drivers
(reportedly igb), where taking RTNL in RPM resume path results in a
deadlock. See [0] for a bug report. I don't think the core changes
are wrong, but taking RTNL in RPM resume path isn't needed.
The Intel drivers are the only ones doing this. See [1] for a
discussion on the issue. Following patch changes the RPM resume path
to not take RTNL.
