net/http: do not discard body content when closing it within request handlers

(*body).Close() internally tries to discard the content of a request
body up to 256 KB. We rely on this behavior to allow connection re-use,
by calling (*body).Close() when our request handler exits.

Unfortunately, this causes an unfortunate side-effect where we would
prematurely try to discard a body content when (*body).Close() is called
from within a request handler.

There should not be a good reason for (*body).Close() to do this when
called from within a request handler. As such, this CL modifies
(*body).Close() to not discard body contents when called from within a
request handler. Note that when a request handler exits, it will still
try to discard the body content for connection re-use.

For #75933
