block: bio-integrity: Copy flags when bio_integrity_payload is cloned

Make sure to copy the flags when a bio_integrity_payload is cloned.
Otherwise per-I/O properties such as IP checksum flag will not be
passed down to the HBA driver. Since the integrity buffer is owned by
the original bio, the BIP_BLOCK_INTEGRITY flag needs to be masked off
to avoid a double free in the completion path.

Fixes: aae7df50 ("block: Integrity checksum flag")
Fixes: b1f01388 ("block: Relocate bio integrity flags")
