Undocumented behaviour in ReqQueryValueEx when 'count' and 'type' point to the same address

WINE's RegQueryValueEx overwrites the value stored at the address
passed in the 'type' parameter early, causing an error in reading a
value from the registry if 'type' and 'count' point to the same
address which doesn't occur in Windows. This patch doesn't address
other undocumented behaviour of calling the function this way, such as
the contents of memory at type and count after the call.
