[PATCH 37/49] x86/alternatives: Move text_poke_array completion from smp_text_poke_batch_finish() and smp_text_poke_batch_flush() to smp_text_poke_batch_process()

[Ingo Molnar]

Simplifies the code and improves code generation a bit:

   text	   data	    bss	    dec	    hex	filename
  14769	   1017	   4112	  19898	   4dba	alternative.o.before
  14742	   1017	   4112	  19871	   4d9f	alternative.o.after
