journal/compress: use LZ4_compress_continue()
We can't use LZ4_compress_limitedOutput_continue() because in the
worst-case scenario the compressed output can be slightly bigger than
the input block. This generally affects very few blocks and is no reason
to abort the compression process.
I ran into this when I noticed that Chromium core dumps weren't being
compressed. After switching to LZ4_compress_continue() a ~330MB Chromium
core dump gets compressed to ~17M.
