[PATCH][BZ #16877] Fix typo in nscd/selinux.c

[Ondřej Bílka]

This bug is another report of typo in code. A perm variable 
is unitialized so there could be spurious error message 
depending how gcc optimizes this. This could be changed into
intended check as below.

OK to commit this?

	[BZ #16877]
	* nscd/selinux.c (nscd_request_avc_has_perm): Check if there is
	nscd security class.
