When a nss plugin returns NSS_STATUS_UNAVAIL with herrno = TRY_AGAIN or NO_DATA,
the no_data variable in gaih_inet() is set to a non-zero value. This variable is
used to signal to the rest of the gaih_inet procedure that no results are
available, which ignores the results of the other plugins.
This value should be reset upon success, like in the patch below:
--- a/sysdeps/posix/getaddrinfo.c 2010-11-22 16:21:19.000000000 -0500
