In l2arc_evict(), the config lock may be acquired in reverse order (e.g., first the config lock (writer), then a hash lock) unlike in arc_read() during scenarios like L2ARC device removal. To avoid deadlocks, if the attempt to acquire the config lock (reader) fails in arc_read(), release the hash lock, wait for the config lock, and retry from the beginning.
