nvmet: report NPDGL and NPDAL
A block device with a very large discard_granularity queue limit may not
be able to report it in the 16-bit NPDG and NPDA fields in the Identify
Namespace data structure. For this reason, version 2.1 of the NVMe specs
added 32-bit fields NPDGL and NPDAL to the NVM Command Set Specific
Identify Namespace structure. So report the discard_granularity there
too and set OPTPERF to 11b to indicate those fields are supported.
