x86/alternatives: Assert input parameters in smp_text_poke_batch_process()

At this point the 'tp' input parameter must always be the
global 'tp_vec' array, and 'nr_entries' must always be equal
to 'tp_vec_nr'.

Assert these conditions - which will allow the removal of
a layer of indirection between these values.
