The issue is with the first add_action function call.

If a function named my_login_logo does not exist in your code, adding an action that would call it will result in the warning or an error.

Looking at the WordPress docs:

https://codex.wordpress.org/Customizing_the_Login_Form

You should use:

function my_login_logo() {
    echo '<style type="text/css">'.
             'h1 a { background-image:url('.get_bloginfo( 'template_directory' ).'/assets/my-logo.png) !important; }'.
         '</style>';
}

add_action( 'login_enqueue_scripts', 'my_login_logo' )

There are a few other examples as well, which includes changing links, further styling, etc.

    2017/06/08 18:25:21 [warn] 5195#5195: *8 an upstream response is buffered to a temporary file /var/lib/nginx/fastcgi/2/00/0000000002 while reading upstream, client: 103.205.112.114, server: mysite.com, request: "GET /wp-admin/load-scripts.php?c=0&load%5B%5D=jquery-core,jquery-migrate,utils,plupload&ver=4.7.5 HTTP/2.0", upstream: "fastcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "mysite.com", referrer: "https://mysite.com/wp-admin/"

It shouldn’t, no, though ultimately the only way to tell if something is impacting performance is to use a monitor or conduct performance metric testing. If you’re not currently seeing higher levels of traffic, it will be a little harder to do that since with low levels of traffic (or no traffic), you can’t really tell unless it is something major.
