Current ectool uses max outsize / insize from protocol v2 even if we have a v3 protocol ec. This makes some command not working when actual size supported by ec is less than max size from protocol v2. This CL uses protoinfo command to read max size from ec during the initialization process to correctly set max size for ec with protocol v3+. For ec with protocol v2, protoinfo command won't exist, hence ectool won't modify the max size and used the size that we set when init the protocol.
