Dmitry Torokhov 9154301a47 HID: hid-input: allow input_configured callback return errors 
When configuring input device via input_configured callback we may
encounter errors (for example input_mt_init_slots() may fail). Instead
of continuing with half-initialized input device let's allow driver
indicate failures.
