habanalabs: zero pci counters packet before submit to FW
Driver does not zero some pci counters packets before sending to FW. This causes an out of sync PI/CI between driver and FW. Signed-off-by: Ofir Bitton <obitton@habana.ai> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
