fgraph: Remove coarse PID filtering from graph_entry()

Browse source

With PID filtering working via ftrace_pids_enabled() and fgraph_pid_func,
the coarse-grained ftrace_trace_task() check in graph_entry() is obsolete.

It was only a fallback for uninitialized op->private (now fixed), and its
removal ensures consistent PID filtering with standard function tracing.

Also remove unused ftrace_trace_task() definition from trace.h.
