[PATCH 1/7] habanalabs: add terminating NULL to attrs arrays

[Oded Gabbay <ogabbay@kernel.org>]

From: Dafna Hirschfeld <dhirschfeld@habana.ai>

Arrays of struct attribute are expected to be NULL terminated.
This is required by API methods such as device_add_groups.
This fixes a crash when loading the driver for Goya device.
