tracing: fprobe: Fix to init fprobe_ip_table earlier
Since the fprobe_ip_table is used from module unloading in
the failure path of load_module(), it must be initialized in
the earlier timing than late_initcall(). Unless that, the
fprobe_module_callback() will use an uninitialized spinlock of
fprobe_ip_table.
Initialize fprobe_ip_table in core_initcall which is the same
timing as ftrace.
