kernel/: fix BUG_ON checks for cpu notifier callbacks direct call
The commit 80b5184cc537718122e036afe7e62d202b70d077 ("kernel/: convert cpu
notifier to return encapsulate errno value") changed the return value of
cpu notifier callbacks.
Those callbacks don't return NOTIFY_BAD on failures anymore. But there
are a few callbacks which are called directly at init time and checking
the return value.
I forgot to change BUG_ON checking by the direct callers in the commit.
