habanalabs: remove in_debug check in device open
The driver supports only a single user anyway, so there is no point in checking whether we are in_debug state when a user tries to open the device, because if we are in_debug, it means a user is already using the device. Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
