HID: appletb-kbd: Fix inconsistent indentation and pass -ENODEV to dev_err_probe

The following warnings were flagged by the kernel test robot:

drivers/hid/hid-appletb-kbd.c:405 appletb_kbd_probe() warn: inconsistent indenting
drivers/hid/hid-appletb-kbd.c:406 appletb_kbd_probe() warn: passing zero to 'dev_err_probe'

This patch aims at fixing those warnings.
