fgraph: Initialize ftrace_ops->private for function graph ops
The ftrace_pids_enabled(op) check relies on op->private being properly
initialized, but fgraph_ops's underlying ftrace_ops->private was left
uninitialized. This caused ftrace_pids_enabled() to always return false,
effectively disabling PID filtering for function graph tracing.
Fix this by copying src_ops->private to dst_ops->private in
fgraph_init_ops(), ensuring PID filter state is correctly propagated.
