[ Upstream commit b6a4bdcda430e3ca43bbb9cb1d4d4d34ebe15c40 ]
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: aae7df50190a ("block: Integrity checksum flag")
Fixes: b1f01388574c ("block: Relocate bio integrity flags")
