denc: only shallow_copy large-enough chunk for decoding

if the bl being decoded is not continous, shallow_copy() will do deep
copy under the hood. this introduces internal fragmentation when
decoding small objects in large non-contiguous bufferlist.

to alleviate this problem, we try to copy less if the object being
decoded is bounded.
