[PATCH 1/2] habanalabs: add rate-limit to an error message

[Oded Gabbay <oded.gabbay@gmail.com>]

This patch changes the print of an error message about mis-configuration
of the debug infrastructure to be rate-limited, to prevent flooding of
kernel log, as these configuration requests can come at a high rate.
