windows: do not corrupt stack with larger boolean return value

Browse Source 
Windows type PBOOL is a pointer to a 4 byte value, where 0 means false
and not-0 means true. That means we should use uint32 here, not bool,
since Go bools can be 1 byte. This commit was re-generated using
mksyscall_windows.go from CL 196122.
