[Qemu-trivial] [PATCH] qemu-sockets: simplify error handling

[Paolo Bonzini]

Just go always through the err label.  (Noticed because Coverity
complains that peer is always non-NULL in the error cleanup code,
but removing the "if" is arguably more prone to introducing the
opposite bug in the future).
