x86/alternatives: Rename 'text_poke_queue()' to 'smp_text_poke_batch_add()'

This name is actively confusing as well, because the simple text_poke*()
APIs use MM-switching based code patching, while text_poke_queue()
is part of the INT3 based text_poke_int3_*() machinery that is an
additional layer of functionality on top of regular text_poke*() functionality.

Rename it to smp_text_poke_batch_add() to make it clear which layer
it belongs to.
