Log:
Add the SYNCHRONIZE flag to the DesiredAccess parameter when using the flags
FILE_SYNCHRONOUS_IO_(NON)ALERT in NtCreateFile or NtOpenFile, even if one uses
DesiredAccess == GENERIC_xxx (which should map to some FILE_GENERIC_xxx already containing
the SYNCHRONIZE flag).
Indeed, it appears after extended testing that, when calling from user-mode, Windows
checks the real presence of the SYNCHRONIZE flag when using FILE_SYNCHRONOUS_IO_(NON)ALERT
even if we pass any of the GENERIC_xxx access flags...
