iomap: don't free integrity payload that doesn't exist
fs_bio_integrity_alloc might not allocate a bio integrity payload if PI
verification is disabled on the block device. Check for that case before
calling fs_bio_integrity_free in iomap_bio_read_folio_range_sync to
avoid a NULL pointer dereferences.
Make the branch cover the PI verification as well - while
fs_bio_integrity_verify works without an integrity payload, it requires
one to actually do useful work.
