rtc: class: fix double free in rtc_register_device() error path

Commit 59cca865f21e ("drivers/rtc/class.c: fix device_register() error
handling") correctly noted that naked kfree() should not be used after
failed device_register() call, however, while it added the needed
put_device() it forgot to remove the original kfree() causing double-free.
