block: inherit BIO_REMAPPED when cloning bios
Cloned bios are can be used to on the same device, in which case we need
to inherit the BIO_REMAPPED flag to avoid a double partition remap. When
the cloned bios are used on another device, bio_set_dev will clear the flag.
Fixes: 309dca309fc3 ("block: store a block_device pointer in struct bio")
