DescEnd will be clipped for alignment in CoreFindFreePagesI, and it may fall below DescStart, when alignment is more than 16KB (included) and both DescStart and original DescEnd fall into a single range of such alignment. This results in a huge size (Negative number in unsigned type) for this descriptor, fulfilling the allocation requirement but failing to run ConvertPages; at last it causes occasional failure of AllocatePages. A simple comparison is added to ensure we would never get a negative number.
