btrfs: Make compress_file_range take only struct async_chunk
All context this function needs is held within struct async_chunk. Currently we not only pass the struct but also every individual member. This is redundant, simplify it by only passing struct async_chunk and leaving it to compress_file_range to extract the values it requires. No functional changes.
