Drivers: hv: vmbus: Perform device register in the per-channel work element
This patch is a continuation of the rescind handling cleanup work. We cannot
block in the global message handling work context especially if we are blocking
waiting for the host to wake us up. I would like to thank
Dexuan Cui <decui@microsoft.com> for observing this problem.
The current char-next branch is broken and this patch fixes
the bug.
