[PATCH] platform/chrome: cros_ec: Initialize panic notifier block

[Chen-Yu Tsai]

Commit d90fa2c64d59 ("platform/chrome: cros_ec: Poll EC log on EC panic")
added a new notifier block, but failed to initialize it properly,
resulting in a warning and stack trace (omitted):

	INFO: trying to register non-static key.
	The code is fine but needs lockdep annotation, or maybe
	you didn't initialize this object before use?
	turning off the locking correctness validator.

Initialize the notifier block properly.
