block: fix blk_integrity_register to use template's interval_exp if not 0
commit 2859323e35ab5fc42f351fbda23ab544eaa85945 upstream.
When registering an integrity profile: if the template's interval_exp is
not 0 use it, otherwise use the ilog2() of logical block size of the
provided gendisk.
This fixes a long-standing DM linear target bug where it cannot pass
integrity data to the underlying device if its logical block size
conflicts with the underlying device's logical block size.
