client: raise ResponseError in _readchannel()

Make it clearer that this is an unrecoverable communication error.
ServerError alone is not always unrecoverable, as CapabilityError is considered
a subtype of it.

This way, a caller can check for ResponseError to identify errors that require
reopening the client to recover.
