Stephen Hemminger e34e92d8b6 hv_netvsc: split sub-channel setup into async and sync ...

[ Upstream commit 3ffe64f1a6 ]

When doing device hotplug the sub channel must be async to avoid
deadlock issues because device is discovered in softirq context.

When doing changes to MTU and number of channels, the setup
must be synchronous to avoid races such as when MTU and device
settings are done in a single ip command.
