SHELL: fixed SHGetFileInfoW

[Alberto Massari <alby@exln.com>]

This patch fixes:

- typo in SHGetFileInfoA (szLoaction instead of szLocation)
- wrong code in SHGetFileInfoW: this function relies on SHGetFileInfoA, so 
it should convert the requested name from Unicode into a multi byte string, 
then copy/convert the data returned in the SHFILEINFOA structure into the 
caller-supplied SHFILEINFOW structure.
The old code was not returning anything to the caller and, depending on 
what was in the provided SHFILEINFOW structure (usually garbage 
characters), it could crash trying to convert two strings from Unicode to 
multi byte.
