x86/entry: Rename trace_hardirqs_off_prepare()
The typical pattern for trace_hardirqs_off_prepare() is:
ENTRY
lockdep_hardirqs_off(); // because hardware
... do entry magic
instrumentation_begin();
trace_hardirqs_off_prepare();
... do actual work
trace_hardirqs_on_prepare();
lockdep_hardirqs_on_prepare();
instrumentation_end();
... do exit magic
lockdep_hardirqs_on();
which shows that it's named wrong, rename it to
trace_hardirqs_off_finish(), as it concludes the hardirq_off transition.
Also, given that the above is the only correct order, make the traditional
all-in-one trace_hardirqs_off() follow suit.
