[PATCH v2 3/6] blk-integrity: take u64 in bio_integrity_intervals()

[Caleb Sander Mateos <csander@purestorage.com>]

To allow bio_integrity_intervals() to convert an absolute sector to an
absolute integrity interval, use u64 for its argument and return types.
Also use SECTOR_SHIFT instead of the magic constant 9.
