misc: lis3lv02d: Change lis3lv02d_init_device() return value for unknown sensors to -ENODEV 

Modern HP laptops do not necessarily actually contain a lis3lv02d
sensor, yet they still define a HPQ6007 device in there ACPI tables.

This leads to the following messages being logged in dmesg:

[   17.376342] hp_accel: laptop model unknown, using default axes configuration
[   17.399766] lis3lv02d: unknown sensor type 0x0
[   17.399804] hp_accel: probe of HPQ6007:00 failed with error -22

The third message is unnecessary and does not provide any useful info,
change the return value for unknown sensors to -ENODEV. This is the
proper return value to indicate that the driver will not be handling the
device and it silences the pr_warn printing the third message.
