mm: percpu: unhide pcpu_embed_first_chunk prototype

Browse source 
Patch series "mm/init/kernel: missing-prototypes warnings".

These are patches addressing -Wmissing-prototypes warnings in common
kernel code and memory management code files that usually get merged
through the -mm tree.


This patch (of 12):

This function is called whenever CONFIG_NEED_PER_CPU_EMBED_FIRST_CHUNK or
CONFIG_HAVE_SETUP_PER_CPU_AREA, but only declared when the former is set:

mm/percpu.c:3055:12: error: no previous prototype for 'pcpu_embed_first_chunk' [-Werror=missing-prototypes]

There is no real point in hiding declarations, so just remove
the #ifdef here.
