redisLibuvPoll crash when server closes the connetion

[mannol]

When server closes the connection, either by shutting down or some protocol irregularity, the libuv adapter crashes in redisLibuvPoll() when calling redisAsyncHandleWrite(). Reason for the crash is that the prior call to redisAsyncHandleRead() frees the context.

I have solved it by placing redisAsyncHandleWrite() before redisAsyncHandleRead(), however, considering that this happens because redisBufferRead(c) == REDIS_ERR causes the __redisAsyncDisconnect(ac) call, the better solution would be to make redisAsyncHandleRead() and redisAsyncHandleWrite() return status.

Hi, I'm going through old issues.

I think this may have been fixed in 9ce15c4. Please reopen if that actually doesn't solve the problem and I will take the time to replicate the bug and submit a patch.
