FmpDevicePkg/FmpDependencyLib: Fix potential overflow in loop

Browse Source 
FmpVersionsCount is a UINTN while the loop index variable compared
against it is a UINT8. This can lead to an overflow of the loop
index for FmpVersionsCount values larger than UINT8_MAX. This change
makes Index a UINTN to match in width.
