[libvirt] [PATCH] libxl: report correct errno from virNetSocketNewConnectTCP on migration

[Ian Campbell]

saved_errno is never written to in this function after it is
initialised and it is only used to log the failure from
virNetSocketNewConnectTCP masking the real errno from that function.

Drop saved_errno and use errno itself.
