Subject: [PATCH] mm: track-active-portions-of-a-section-at-boot-fix fix

A bugfix introduced a new warning as it marked a function as __init
that is called by both __init and non-__init functions:

WARNING: vmlinux.o(.text.unlikely+0x1b26): Section mismatch in reference from the function section_deactivate() to the function .init.text:section_active_mask()
WARNING: vmlinux.o(.meminit.text+0x1ce0): Section mismatch in reference from the function sparse_add_section() to the function .init.text:section_active_mask()

This removes the annotation again.

Fixes: mmotm ("mm-track-active-portions-of-a-section-at-boot-fix")
