ethip6: forward correct error code

Browse Source 
On failure, nd6_get_next_hop_entry() returns an ERR_ type negative
error code.  ethip6_output() erroneously assumed that that error would
always be ERR_MEM, even though it may also be ERR_RTE in practice.
With this patch, ethip6_output() simply forwards the returned error.
