CHIPS: Fix potential starvation in cfi_cmdset_0001
The patch below fixes a potential starvation issue that can arise when there is contention on a chip during a period when a process is currently writing to it. The starvation is avoided by conditionally rescheduling when the chip is left in a state usable by other processes.
