ptrace/m68k: Stop open coding ptrace_report_syscall
The generic function ptrace_report_syscall does a little more than syscall_trace on m68k. The function ptrace_report_syscall stops early if PT_TRACED is not set, it sets ptrace_message, and returns the result of fatal_signal_pending. Setting ptrace_message to a passed in value of 0 is effectively not setting ptrace_message, making that additional work a noop. Returning the result of fatal_signal_pending and letting the caller ignore the result becomes a noop in this change. When a process is ptraced, the flag PT_PTRACED is always set in current->ptrace. Testing for PT_PTRACED in ptrace_report_syscall is just an optimization to fail early if the process is not ptraced. Later on in ptrace_notify, ptrace_stop will test current->ptrace under tasklist_lock and skip performing any work if the task is not ptraced.
