clang sometimes decides not to inline shuffle_zone(), but it calls a
__meminit function.  Without the extra __meminit annotation we get this
warning:

  WARNING: modpost: vmlinux.o(.text+0x2a86d4): Section mismatch in reference from the function shuffle_zone() to the function .meminit.text:__shuffle_zone()
  The function shuffle_zone() references
  the function __meminit __shuffle_zone().
  This is often because shuffle_zone lacks a __meminit
  annotation or the annotation of __shuffle_zone is wrong.

shuffle_free_memory() did not show the same problem in my tests, but it
could happen in theory as well, so mark both as __meminit.
