Make probe_cores deal with an unconfigured FPGA (and come back later).
See, reading from an unconfigured FPGA returns all-1, while reading from empty cores on a configured FPGA returns all-0. The consequence of this is that the HSM was probing the FPGA once on startup, filling its core table with 0xff, rendering the FPGA useless. Along the way, I put the FPGA core table in static memory, rather than malloc'ing it, because that's not so good in an embedded environment. But I kept the linked list, because that at least tells us what to do if HAL_STATIC_CORE_STATE_BLOCKS is 0.
