It's info message reporting that client closed keepalive
connection, nothing more. This may and will happen under normal
use.

This is another info message, reporting that client closed
connection before nginx was able to send full response to it.
This is normal as well and may happen e.g. if browser is closed or
user navigated to another page.

If you don't see such mesages - just tune your error_log logging
level to something less verbose. Something like "notice" or
"error" is usually a good choice for production.
