btrfs: don't clear async_chunk->inode in async_cow_start

Now that the ->inode check isn't needed in submit_compressed_extents
any more, there is no reason to clear the field early.  Always keep
the inode around until the work item is finished and remove the special
casing, and the counting of compressed extents in compress_file_range.
