[PATCH] Fix 'array subscript is above array bounds' warning in res_send.c

[Siddhesh Poyarekar]

Hi,

I see this warning in my build on F21 x86_64, which seems to be due to
a weak check for array bounds.  Fixed by making the bounds check
stronger.

OK to commit?

	* resolv/res_send.c (__libc_res_nsend): Fix check for nsmap
	bounds.
