fix section error

__apicid_to_node can no longer be __cpuinit as it is referred to from
acpi_unmap_lsapic().

>> WARNING: vmlinux.o(.text+0x43773): Section mismatch in reference from the function acpi_unmap_lsapic() to the variable .cpuinit.data:__apicid_to_node
   The function acpi_unmap_lsapic() references
   the variable __cpuinitdata __apicid_to_node.
   This is often because acpi_unmap_lsapic lacks a __cpuinitdata
   annotation or the annotation of __apicid_to_node is wrong.
