ethtool: Remove unnecessary null check in ethtool_rx_flow_rule_create

Browse Source 
net/core/ethtool.c:3023:19: warning: address of array
'ext_m_spec->h_dest' will always evaluate to 'true'
[-Wpointer-bool-conversion]
                if (ext_m_spec->h_dest) {
                ~~  ~~~~~~~~~~~~^~~~~~

h_dest is an array, it can't be null so remove this check.
