upload_space_check_disabled in upload_is_user_over_quota()

wp-includes/ms-functions.php, line 1106:

function upload_is_user_over_quota( $echo = true ) {
	if ( get_site_option( 'upload_space_check_disabled' ) )
		return true;
	...
}

I guess it's hard to exceed space quota when upload space check is disabled :) So we should return false.

It seems the control never gets there in this case, though.

(In [16299]) Return false if upload_space_check_disabled is true in upload_is_user_over_quota(). Props SergeyBiryukov. fixes #14121
