[ 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.

Fixes: 7b2ee50c ("hv_netvsc: common detach logic")
