alpha: Replace strncmp with str_has_prefix
In commit b6b2735514bc ("tracing: Use str_has_prefix() instead of using fixed sizes") the newly introduced str_has_prefix() was used to replace error-prone strncmp(str, const, len). Here fix codes with the same pattern. Signed-off-by: Chuhong Yuan <hslester96@gmail.com> Signed-off-by: Matt Turner <mattst88@gmail.com>
