Drivers: hv: vmbus: Add timeout to vmbus_wait_for_unload
[ Upstream commit 911e1987efc8f3e6445955fbae7f54b428b92bd3 ]
vmbus_wait_for_unload() looks for a CHANNELMSG_UNLOAD_RESPONSE message
coming from Hyper-V. But if the message isn't found for some reason,
the panic path gets hung forever. Add a timeout of 10 seconds to prevent
this.
