rgw/posix: fix event replay in BucketCache ev_loop

evec is never cleared after each n->notify() call, so events accumulate
across iterations of ev_loop's inner for loop. Each notify() call
receives not just the current event but all events dispatched in earlier
iterations too.

Add evec.clear() after each n->notify() call.
