[PATCH] ftrace: avoid redundant initialization in register_ftrace_direct

[Menglong Dong]

The FTRACE_OPS_FL_INITIALIZED flag is cleared in register_ftrace_direct,
which can make it initialized by ftrace_ops_init() even if it is already
initialized. It seems that there is no big deal here, but let's still fix
it.
