WS_getpeername buffer length fix

[Paul Rupe]

While running the Win32 version of perl under Wine (don't ask), I 
noticed that WS_getpeername wasn't returning the length of the output if 
the buffer was larger than needed.  The app was calling getpeername with 
a 256-byte buffer and expecting *namelen to be 16 afterward.  The most 
logical place to fix this was in ws_sockaddr_u2ws.  Other APIs call this 
function, but I think they would also expect the same behavior so it 
should be ok.

The one-line addition below takes care of the problem.

  Return length of WS_sockaddr structure in ws_sockaddr_u2ws.
