### Description of problem:

Apache httpd does not log status code "413" in access_log when hitting LimitRequestBody. It logs status code "200" instead. 


### Version-Release number of selected component (if applicable):

httpd-2.4.6-40.el7_2.4.x86_64


### How reproducible:

Anytime


### Steps to Reproduce:

1. Configure LimitRequestBody and mod_ext_filter:

    LimitRequestBody 100

2. Prepare a test file which is larger than LimitRequestBody

    dd if=/dev/zero of=/tmp/testfile bs=1 count=101

3. Sent a POST request with the file 

    curl -X POST -vs -T /tmp/testfile http://127.0.0.1/index.html

   or

    curl -X POST -vs -H "Transfer-Encoding: chunked" -F "test=@/tmp/testfile" http://127.0.0.1/index.html


### Actual results:

"413 Request Entity Too Large" was returned to the client (curl) and the following log messages were output in error_log:

~~~
[Fri Sep 02 21:05:03.488793 2016] [http:info] [pid 4790] [client 127.0.0.1:59214] AH01588: Requested content-length of 101 is larger than the configured limit of 100
[Fri Sep 02 21:05:20.864884 2016] [http:info] [pid 4791] [client 127.0.0.1:59216] AH01591: Read content length of 152 is larger than the configured limit of 100
~~~

But status code 413 was not logged but status code 200 was logged instead in access_log:

~~~
127.0.0.1 - - [02/Sep/2016:21:05:03 +0900] "POST /index.html HTTP/1.1" 200 339 "-" "curl/7.29.0" "Cookie: -" "Set-Cookie: -" 0 711
127.0.0.1 - - [02/Sep/2016:21:05:20 +0900] "POST /index.html HTTP/1.1" 200 339 "-" "curl/7.29.0" "Cookie: -" "Set-Cookie: -" 0 719
~~~


### Expected results:

status code 413 should be output in access_log.
