nvme/host: Add missing blk_integrity tag_size + flags assignments
While doing recent bring-up of nvme/host with target-core T10-PI,
I noticed /sys/block/nvme*/integrity/device_is_integrity_capable
was false, and /sys/block/nvme*/integrity/tag_size contained
a bogus value.
AFAICT outside of blk_integrity_compare() for DM + MD these
are informational values, but go ahead and add the missing
assignments for nvme/host to match what SCSI does within
sd_dif_config_host() for consistency's sake.
