eql: use __dev_get_by_name instead of dev_get_by_name to find interface
The following call chain indicates that eql_ioctl(), eql_enslave(),
eql_emancipate(), eql_g_slave_cfg() and eql_s_slave_cfg() are
protected under rtnl_lock. So if we use __dev_get_by_name() instead
of dev_get_by_name() to find interface handlers in them, this would
help us avoid to change interface reference counters.
dev_ioctl()
rtnl_lock()
dev_ifsioc()
eql_ioctl()
eql_enslave()
eql_emancipate()
eql_g_slave_cfg()
eql_s_slave_cfg()
rtnl_unlock()
Additionally we also change their return values from -EINVAL to
-ENODEV in case that interfaces are no found.
