Christoph Hellwig 45686b6198 nvme: fix max_segments integer truncation ...

The block layer uses an unsigned short for max_segments.  The way we
calculate the value for NVMe tends to generate very large 32-bit values,
which after integer truncation may lead to a zero value instead of
the desired outcome.
