Windows: log FSCTL_CSC_INTERNAL requests

FSCTL_CSC_INTERNAL requests are not supported and will
return STATUS_INVALID_DEVICE_REQUEST.  However, log them
for easier debugging.

FSCTL_CSC_INTERNAL is defined in ntifs.h only for
Vista and above.  Since afsredir is built for XP
and above its value must be conditionally defined
by us.
