Fix a bug of ixg(4)'s media setting.

Before:
 ifconfig ixg0 media 100baseTX  -> advertise 100Mbps only
 ifconfig ixg0 media 1000baseT  -> advertise 1Gbps and 1000Mbps (NG)
 ifconfig ixg0 media 10Gbase-T  -> advertise all (NG)
 ifconfig ixg0 media auto       -> advertise all

After:
 ifconfig ixg0 media 100baseTX  -> advertise 100Mbps only
 ifconfig ixg0 media 1000baseT  -> advertise 1Gbps only
 ifconfig ixg0 media 10Gbase-T  -> advertise 10Gbps only
 ifconfig ixg0 media auto       -> advertise all
