IB/ehca: Misc cpuinit section annotations and #ifdef cleanups
* Replace {un}register_cpu_notifier with {un}register_hotcpu_notifier
thereby losing a couple of #ifdef HOTPLUG_CPU pairs.
* Move comp_pool_callback_nb declaration to below that of callback
function so that initialization of .notifier_call and .priority can
occur at build time itself and not runtime.
* Mark the notifier_block (and callback function, and another static
function used by it) as __cpuinit{data} for the sake of consistency
and remove enclosing #ifdef. (This may increase size for modular
build of this module, however, because these are no longer dropped
unconditionally now.)
