btrfs: check correct bio in finish_compressed_bio_read

Browse Source 
Commit c09abff87f ("btrfs: cloned bios must not be iterated by
bio_for_each_segment_all") added ASSERT()'s to make sure we weren't
calling bio_for_each_segment_all() on a RAID5/6 bio.  However it was
checking the bio that the compression code passed in, not the
cb->orig_bio that we actually iterate over, so adjust this ASSERT() to
check the correct bio.
