Few of the notifier_chain_register() callers use __initdata in
the definition of notifier_block data structure. It is incorrect as
the data structure should be available after the initializations (they
do not unregister them during initializations).
This was leading to oops when notifier_chain_register() call is invoked
for those callback chains after initialization.
This patch fixes all such usages to _not_ have the notifier_block data
structure in the init data section.
