2013-09-10dpaa_eth: Fix draining of buffer poolsIoana Radulescu
When draining buffers in batches of eight, we must take into account the fact that BMan will return an error code if there are less than eight buffers left in the pool; when this happens, drain the remaining buffers one by one. And since we're at buffer pool cleanup, make sure allocated bpools get freed in case of errors inside the probe function.
