When health & performance data is requested from the controller,
it responds with an error log containing the requested information.
This patch allows the request to me issued via an IOCTL.
A better explanation would be good - this IOCTL triggers a request to
the controller to collect controller health/perf data, and the
controller will later respond with an error log that can be picked up
via the error log IOCTL that you've defined earlier.
