[PATCH net-next] hv_netvsc: fix error return code in netvsc_probe()

[Wei Yongjun]

Fix to return a negative error code from the failover register fail
error handling case instead of 0, as done elsewhere in this function.

Fixes: 1ff78076d8dd ("netvsc: refactor notifier/event handling code to use the 
failover framework")
