There are two read op on the same object for ec pool. First op read
miss happend, call do_proxy_read and promote_object, The second op only
do_proxy_read. but before call process_copy_chunk for first op and then
finish_proxy_read for second op, first op receive reply from base pool
first and then second received. so the second op reset the field "outdata"

cancel_proxy_read for second op and then requeue it. At last in do_osd_ops,
it append outdata field.
