nss: remove dead code
c > 0 is already guaranteed from earlier checks.
We go from
ms = ALIGN(l+1) +
sizeof(char*) +
(c > 0 ? c : 1) * ALIGN(alen) +
(c > 0 ? c+1 : 2) * sizeof(char*);
to
ms = ALIGN(l+1) +
sizeof(char*) +
c * ALIGN(alen) +
(c+1) * sizeof(char*);
to
ms = ALIGN(l+1) + c * ALIGN(alen) + (c+2) * sizeof(char*);
Found by coverity. Fixes: CID#1237570 and CID#1237610
