rS310084: Don't run the MCA record refill task during boot.

Summary

If we take a CMCI during boot (between SI_SUB_CPU and SI_SUB_CONFIGURE)
before the refill task is initialized, we'll panic otherwise. Instead, predicate use of
the taskqueue on !cold and make sure that we've refilled the record list when starting
the taskqueue thread.
