Sometimes the chipset task is slow enough that we might get messages from the AP before chipset_in_state(CHIPSET_STATE_ON) is true. This causes us to leave the spi off after our usual reset after every transaction (see chrome-os-partner:31390). This would put an end to any EC communications. Instead of relying on CHIPSET_STATE_ON we could just save the value of "enabled" before we turn it off, then use that as a condition instead. There shouldn't be a race condition on "enabled" because the only other place it gets modified is in the hooks, which can't preempt spi_init (which usually happens in the host command task). The only problem is that in case of a sysjump enabled will be 0, so CHIPSET_STATE_ON was left as a backup to handle that case.
