[PATCH] avoid double Nul termination

[Thorsten Kukuk]

Hi,

As result of Bug #962 I double checked the code and remove the
assert statements, the string is always Nul terminated in our yp_match
implementation. I still don't understand why malloc_usable_size
returns the wrong value, but this patch is save and only removes the
duplicate Nul termination:

	[BZ #962]
	* nis/nss_nis/nis-netgrp.c (_nss_nis_setnetgrent): Remove
	double Nul termination.
