wintab32: fixing a typo which prevented sending correct pkSerialNumber

[Eriks Dobelis]

This submission Obsoletes patch id#103302. I split it into parts for 
easier review and will later submit the rest of patches, but each of 
them will resolve a single issue and they are not interdependent. Common 
goal is to resolve http://bugs.winehq.org/show_bug.cgi?id=18517.

This patch fixes a typo in a code, which was a cause for wrong 
pkSerialNumber values to be sent in messages. TRACE entries showed 
correct values, because TRACE statement was executed before actual 
sending of the packet. Due to this it took quite a time to spot the 
problem :)
