bgpd: refactor type of srv6_locator_chunks list

Since additional information such as block_bits_length is needed to
generate SIDs properly, the type of elements in srv6_locator_chunks
list is extended from "struct prefix_ipv6 *" to
"struct srv6_locator_chunk *". Even in terms of variable name,
"struct srv6_locator_chunk *" is appropriate.
