The original code had no way to handle it, and msdn doesn't mention how 
to handle this. The original code would leak 256 bytes and still be able 
to overflow, so I think this is still an improvement, considering the 
alternatives suck harder.

One way would be to put the wide versions of the strings in 
DSDRIVERDESC->pvReserved1/2 so we could do this without leaks and 
conversions, but since this will make it harder to just drop in an older 
wine driver to test if a problem goes away, I felt that keeping the leak 
is probably the least evil way to handle this, considering typically 
this code is only called once in the entire lifespan of a program at 
most. Most programs will use DSPROPERTY_Enumerate, which doesn't leak.

Cheers,
Maarten.
