patch to dlls/user32/msg16.c to prevent unhandled memory exception

This patch to the DispatchMessage16 function of dlls/user32/msg16.c also fixes
an exception that occured after coming back from the callback. The msg pointer
then points nowhere. Contrary to the previous patch, the original
segment:offset is lost by the implicit conversion done by the relay16.c
routines so I used another way (a temporary local copy of the structure).

This is my last patch for the day. Enjoy!
