[libvirt] [PATCH v2] Fix connection to already running session libvirtd

Since 1b807f92, connecting with virsh to an already running session
libvirtd fails with:
$ virsh list --all
error: failed to connect to the hypervisor
error: no valid connection
error: Failed to connect socket to
'/run/user/1000/libvirt/libvirt-sock': Transport endpoint is already

This is caused by a logic error in virNetSocketNewConnectUnix: even if
the connection to the daemon socket succeeded, we still try to spawn the
daemon and then connect to it.
This commit changes the logic to not try to spawn libvirtd if we
successfully connected to its socket.

Most of this commit is whitespace changes, use of -w is used to look at
Same patch as the previous but with -w for easier review
