usbnet: ipheth: Remove unnecessary NULL pointer check
ipheth_carrier_set() is called from two locations. In
ipheth_carrier_check_work(), its parameter 'dev' is set with
container_of(work, ...) and can not be NULL. In ipheth_open(),
dev is extracted from netdev_priv(net) and dereferenced before
the call to ipheth_carrier_set(). The NULL pointer check of dev
in ipheth_carrier_set() is therefore unnecessary and can be removed.
