[PATCH] xen/netback: fix error path of xenvif_connect_data()

[Juergen Gross]

xenvif_connect_data() calls module_put() in case of error. This is
wrong as there is no related module_get().

Remove the superfluous module_put().

Fixes: 279f438e36c0a7 ("xen-netback: Don't destroy the netdev until the vif is shut down")
