HID: wacom: fix memory leak on sysfs attribute creation failure

When sysfs_create_files() fails during wacom_initialize_remotes() the
fifo buffer is not freed leading to a memory leak.

Fix this by calling kfifo_free() before returning.

Fixes: 83e6b40e2de6 ("HID: wacom: EKR: have the wacom resources dynamically allocated")
