When we run out of buffer space and set result to NSS_STATUS_TRYAGAIN and errno
to ERANGE, and we're also setting h_errno, set it to NETDB_INTERNAL, which libc
also checks when it's available.  The _nss_ldap_getbyname function will already
have set errno for us, so we go with the patch as used rather than the original
one, which also set errno here.
