x86/cpu_entry_area: Annotate percpu_setup_exception_stacks() as __init

Browse Source 
After a recent LLVM change that deduces __cold on functions that only call
cold code (such as __init functions), there is a section mismatch warning
from percpu_setup_exception_stacks(), which got moved to .text.unlikely. as
a result of that optimization:

  WARNING: modpost: vmlinux: section mismatch in reference:
  percpu_setup_exception_stacks+0x3a (section: .text.unlikely.) ->
  cea_map_percpu_pages (section: .init.text)

Drop the inline keyword, which does not guarantee inlining, and replace it
with __init, as percpu_setup_exception_stacks() is only called from __init
code, which clears up the warning.
