HID: wacom: fix memory leak on kobject creation failure

During wacom_initialize_remotes() a fifo buffer is allocated
with kfifo_alloc() and later a cleanup action is registered
during devm_add_action_or_reset() to clean it up.

However if the code fails to create a kobject and register it
with sysfs the code simply returns -ENOMEM before the cleanup
action is registered leading to a memory leak.

Fix this by ensuring the fifo is freed when the kobject creation
and registration process fails.
