ichspi.c: Bug fix for ich_hwseq_get_flash_id

In ich_hwseq_get_flash_id, flash_id_to_entry would return
address of a structure present in flashchips array
corresponding to provided manufacture_id and model_id.
If this function returns NULL and if we don't return
after printing the warning using msg_pwarn, we'll be
dereferencing a NULL pointer, hence the return in that
if is provided.
