hv_netvsc: Fix error handling in netvsc_attach()
[ Upstream commit
719b85c336ed35565d0f3982269d6f684087bb00 ]
If rndis_filter_open() fails, we need to remove the rndis device created
in earlier steps, before returning an error code. Otherwise, the retry of
netvsc_attach() from its callers will fail and hang.
