powerpc/code-patching: Use jump_label to check if poking_init() is done
It's only during early startup that poking_init() is not done yet,
for instance when calling ftrace_init().
Once poking_init() has been called there must be a poking area, no
need to check it everytime patch_instruction() is called.
ftrace activation time is reduced by 7% with the change on an 8xx.
