ublk: report BLK_SPLIT_INTERVAL_CAPABLE
The ublk driver doesn't access request integrity buffers directly, it
only copies them to/from the ublk server in ublk_copy_user_integrity().
ublk_copy_user_integrity() uses bio_for_each_integrity_vec() to walk all
the integrity segments. ublk devices are therefore capable of handling
requests with integrity intervals split across segments. Set
BLK_SPLIT_INTERVAL_CAPABLE in the struct blk_integrity flags for ublk
devices to opt out of the integrity-interval dma_alignment limit.
