[PATCH] Input: amijoy - fix memory region leak on registration failure

[Thorsten Blum <blum@kernel.org>]

If input_register_device() fails in amijoy_init(), release the memory
region for port i before cleaning up the previously registered ports.

Fixes: 127278ce2254 ("Input: joysticks - handle errors when registering input devices")
