[PATCH] platform: x86: hp_wireless: Inform the user if hp_wireless_input_setup()/add() fails

[Giedrius Statkevicius]

In hpwl_add() there is a unused variable err to which we assign the
result of hp_wireless_input_setup() but we don't do anything depending
on the result so print out a message that informs the user if add()
(hp_wireless_input_setup()) fails since acpi_device_probe() doesn't
print anything in this case.
