fix build on 5-CURRENT after RFC3542 change (EAI_ADDRFAMILY and

EAI_NODATA were obsoleted).

There is some issue; we have EAI_NODATA as an alias of EAI_NONAME
for workaround.  However, some of these ports use it as a case
label of switch.  Since our alias broke such code, we may better
to consider deleting such alias.
