Fix incorrect map usage in the WebPluginImpl::didReceiveData function, which caused a response to be incorrectly treated as a multipart response. This would eventually end up sending the ViewHostMsg_DidStopLoading IPC to the browser, which would treat the page as loaded, when it has not. 
Fix incorrect map usage in the WebPluginImpl::didReceiveData function, which caused
a response to be incorrectly treated as a multipart response. This would eventually
end up sending the ViewHostMsg_DidStopLoading IPC to the browser, which would treat the
page as loaded, when it has not. 

This fixes http://code.google.com/p/chromium/issues/detail?id=7916, which would cause
the favicon to not show up on trunk.
