scripts/clang-tools: Remove DeprecatedOrUnsafeBufferHandling check
This `clang-analyzer` check flags the use of memset(), suggesting a more secure version of the API, such as memset_s(), which does not exist in the kernel: warning: Call to function 'memset' is insecure as it does not provide security checks introduced in the C11 standard. Replace with analogous functions that support length arguments or provides boundary checks such as 'memset_s' in case of C11 [clang-analyzer-security.insecureAPI.DeprecatedOrUnsafeBufferHandling] Signed-off-by: Guru Das Srinagesh <quic_gurus@quicinc.com> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
