[PATCH OLK-5.10] bnxt: Do not read past the end of test names

From: Nikolay Kuratov <kniv(a)yandex-team.ru> stable inclusion from stable-v5.10.235 commit ca381f60a3bb7cfaa618d73ca411610bd7fc3149 category: bugfix bugzilla: 189268 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a1a7eb89ca0b89dc1c326eeee2596f263291aca3 upstream.
