[PATCH] Return EAI_AGAIN for AF_UNSPEC when herrno is TRY_AGAIN (BZ #16849)

getaddrinfo correctly returns EAI_AGAIN for AF_INET and AF_INET6
queries.  For AF_UNSPEC however, an older change
(a682a1bf553b1efe4dbb03207fece5b719cec482) broke the check and due to
that the returned error was EAI_NONAME.

This patch fixes the check so that a non-authoritative not-found is
returned as EAI_AGAIN to the user instead of EAI_NONAME.

Tested on x86_64.


	[BZ #16849]
	* sysdeps/posix/getaddrinfo.c (gaih_inet): Only check for
	herrno to return EAI_AGAIN.
