[PATCH 2/4] HID: lamparray: raise log level of fatal probe errors

[Cristian Mazzotta <cmmazzo@icloud.com>]

The failure paths in lamparray_read_attributes_report() and
lamparray_get_lamp_attributes() use hid_dbg(), so on a device that
cannot be driven the driver declines to register with no output unless
dynamic debug is enabled for the module.

Use hid_warn() for these, since they leave the device without LED
support and the reason is useful to anyone diagnosing why a LampArray
device did not appear under /sys/class/leds.
