bio_uncompress_inplace() used to potentially need to extend the bio to
be big enough for the uncompressed data, which has become problematic
with multipage bvecs - but, the move extent path actually already
allocated the bios to be big enough for the uncompressed data.
The promote path needed to be fixed, though.

Switch to always using bio_add_page(), which merges contiguous pages now
that we have multipage bvecs.
