Fix possible integer overflow in MtpStorage

When converting the MB value MtpReserveSpace value to bytes there is a
possible integer overflow since 3 integer values are multiplied, even
though the result is stored in a long variable. This would be visible when
the value is more than 2 GB. This is solved by making the constants
longs instead of ints.
