(verify_volume): Call set_next_block_after

if read_header returns HEADER_FAILURE
Destroy and reinitialize content of current_stat_info and
extended_header after each iteration.
Issue a warning if the archive created contains some members
whose file names were stripped off their leading prefixes.
This is a temporary fix of the issue reported by Bdale Garbee
