Drivers that manage inline-encrypted I/O directly need to advance the DUN across bio_vecs within a bio, or across multiple bios in a request, and have no other way to call this function. Move the declaration from block/blk-crypto-internal.h to include/linux/blk-crypto.h alongside the existing bio_crypt_dun_is_contiguous() and blk_crypto_init_key() declarations. The implementation in block/blk-crypto.c is unchanged.
