init: Invoke init_espfix_bsp() from mm_init()
commit 613e396bc0d4c7604fba23256644e78454c68cf6 upstream.
init_espfix_bsp() needs to be invoked before the page table isolation
initialization. Move it into mm_init() which is the place where pti_init()
will be added.
While at it get rid of the #ifdeffery and provide proper stub functions.
