Shengming Hu 47d1f7e785 fgraph: Check ftrace_pids_enabled on registration for early filtering 
commit 1650a1b6cb upstream.

When registering ftrace_graph, check if ftrace_pids_enabled is active.
If enabled, assign entryfunc to fgraph_pid_func to ensure filtering
is performed before executing the saved original entry function.
