ftrace: Remove data field from ftrace_func_probe structure
No users of the function probes uses the data field anymore. Remove it, and change the init function to take a void *data parameter instead of a void **data, because the init will just get the data that the registering function was received, and there's no state after it is called. The other functions for ftrace_probe_ops still take the data parameter, but it will currently only be passed NULL. It will stay as a parameter for future data to be passed to these functions.
