UPSTREAM: f2fs: update_sit_entry_for_release() supports consecutive blocks.

This function can process some consecutive blocks at a time.

When using update_sit_entry() to release consecutive blocks,
ensure that the consecutive blocks belong to the same segment.
Because after update_sit_entry_for_realese(), @segno is still
in use in update_sit_entry().
