audit: Fix check of return value of strnlen_user()

[ Upstream commit 0b08c5e59441d08ab4b5e72afefd5cd98a4d83df ]

strnlen_user() returns 0 when it hits fault, not -1. Fix the test in
audit_log_single_execve_arg(). Luckily this shouldn't ever happen unless
there's a kernel bug so it's mostly a cosmetic fix.
