Describe the bug:
During the processing of the minerprotocols survey task, we hit a panic.
daemon panic: runtime error: invalid memory address or nil pointer dereference

Looks like a nil is being returned from api.StateMinerInfo(ctx, miner, headTs.Key()) even though no error is being return.
Steps to Reproduce:
Run minerprotocols survey task. Wait until the API finds itself in the condition that causes api.StateMinerInfo(ctx, miner, headTs.Key()) to return nil, nil. 😢
