[PATCH] Fix segv in nss_files

[Jakub Jelinek]

Hi!

With multi on in /etc/host.conf and lines like:
1.2.3.4 x
1.2.3.4 x y
in /etc/hosts gethostbyname segfaults (a while loop in HOST_DB_LOOKUP loops
forever because cnt is never incremented).
Fixed by following patch.

	* nss/nss_files/files-hosts.c (HOST_DB_LOOKUP): Increment counter in
	the loop.
