spi: Call clear_spi_id_cache() before probing next chip

The original author David Hendricks 
introducted the clear_spi_id_cache() however it seems this
was actually never used before attempting a new probe_flash()
cycle.

<NOT-FOR-MERGE-YET> unclear what was originally intended here.

BUG=b:224375126
TEST=`./flashrom -p internal --flash-name`.
