Changpeng Liu 04cd292237 nvme/quirk: add MDTS excludes interleaved metadata quirk 
The specification for Maximum Data Transfer Size (MDTS) says this field
should include the length of metadata, if metadata is interleaved with the
logical block data.  However, some drives can support MDTS without counting
the interleaved metadata, so for this case SPDK will only use data length
without interleaved metadata length.
