compat/win32mmap.c: Fix some sparse warnings

Sparse issues two 'Using plain integer as NULL pointer' warnings
against the call to the CreateFileMapping() function. The warnings
relate to the second and sixth parameters, which both have pointer
type. In order to suppress the warnings, we simply pass the NULL
pointer, rather than '0', to those parameters in the function call.
