Subject: rgw: shouldn't call index_op.cancel() when rados op return ETIMEDOUT

rgw: shouldn't call index_op.cancel() when rados op return ETIMEDOUT

when rados op return ETIMEOUT, rgw can't determine whether or not the rados op succeeded,
we shouldn't be calling index_op->cancel() in this case
Instead, we should leave that pending entry in the index so than bucket listing can recover with check_disk_state() and cls_rgw_suggest_changes()
