x86/alternatives: Rename 'text_poke_loc_init()' to 'text_poke_int3_loc_init()'

This name is actively confusing as well, because the simple text_poke*()
APIs use MM-switching based code patching, while text_poke_loc_init()
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 text_poke_int3_loc_init() to make it clear which layer
it belongs to.
