cls/rgw: adjust types and ops

 - don't keep data bufferlist in struct cls_rgw_bucket_instance_entry
 - remove rgw_get_bucket_instance

We need to keep the reshard info as part of the bucket index header (for
each source bucket shard), and not in a separate object. Otherwise it'll
be impossible to have the resharding check atomic as part of the regular
bucket index updates.

os/bluestore: release aios and pinned buffers on io complete

Once we're done with our IO, clear the aio list so that the pinned buffers
are unpinned.  This ensures we release memory quickly, even if the
TransContext sticks around for a while (e.g., in the osr q).

os/bluestore: submit deferred if txc cleanup is blocked

If we have a single deferred write, and then a uniform workload with *no*
deferred writes, we will never actually submit it.  Meanwhile, the txc is
stuck on the osr q and nothing ever gets retired.

Simple fix is to submit any deferred ops if the osr queue is blocked by
a queued deferred write and the osr queue length is above some
threshold.  This prevents memory from being pinned indefinitely.
