Subject: kernel/notifier.c: remove notifier_chain_cond_register()

The only difference between notifier_chain_cond_register() and
notifier_chain_register() is the lack of warning hints for duplicate
registrations.  Use notifier_chain_register() instead of
notifier_chain_cond_register() to avoid duplicate code
