[PATCH] um: vector: always reset vp->opened

[Johannes Berg]

From: Johannes Berg <johannes.b...@intel.com>

If open fails, we have already set vp->opened, but it's
not reset so that any further attempts will just return
-ENXIO. Reset vp->opened even if close has nothing to do.

This helps e.g. with slirp4netns handling only a single
connection, you can then restart it and open the device
again.
