stephen hemminger 9b4e946ce1 netvsc: fix deadlock betwen link status and removal 
There is a deadlock possible when canceling the link status
delayed work queue. The removal process is run with RTNL held,
and the link status callback is acquring RTNL.

Resolve the issue by using trylock and rescheduling.
If cancel is in process, that block it from happening.

Fixes: 122a5f6410 ("staging: hv: use delayed_work for netvsc_send_garp()")
