a simple checker for AsyncRequestWorkerFactor

Hi, 

In mpm_event (server/mpm/event/event.c), there're some minor checking problem for the AsyncRequestWorkerFactor directive, which makes the configuration checking style inconsistent. 

Basically, if the input is a negative value, the code converts it to a super big unsigned integer. I suggest to add a checker like all the other module directives do. For example, LimitRequestLine, LimitRequestFieldsize, CacheMin/MaxFileSize, etc. I personally really like the idea of careful checking in Apache httpd.

The patch is really simple and tested.

Thanks,
Jackie
