[PATCH] nvme-cli: Fix the displayed metadata length value on Big Endian systems.

[PATCH] nvme-cli: Fix the displayed metadata length value on Big Endian systems.

[Jeff Lien]

On BE systems, the metadata length value displayed as part of the
format in the nvme list command is byte swapped.  So a value of 0
appears just fine but a value of 8 bytes is displayed as 0x0800.
This patch fixes that is the value is correct for both LE and BE
systems.
