Add NULL check in the avs_component_probe

When devm_kasprintf() fails, it returns a NULL pointer. However, this return value is not properly checked in the function avs_component_probe. 

A NULL check should be added after the devm_kasprintf call to handle potential NULL pointer dereference error.

CODE:
		if (((vendor_id >> 16) & 0xFFFF) == 0x8086)
			mach->tplg_filename = devm_kasprintf(adev->dev, GFP_KERNEL,
							     "hda-8086-generic-tplg.bin");
		else
			mach->tplg_filename = devm_kasprintf(adev->dev, GFP_KERNEL,
							     "hda-generic-tplg.bin");

		filename = kasprintf(GFP_KERNEL, "%s/%s", component->driver->topology_name_prefix,
				     mach->tplg_filename);
