mb/google/zork/smihandler: only print warning in mainboard_smi_gpi

zork doesn't configure any GPIO as PAD_SMI. Since mainboard_smi_gpi will
only get called for a GEVENT that will cause a non-SCI SMI, this isn't
expected to be called. For the unexpected and very unlikely case that it
still does get called, put a printk into mainboard_smi_gpi to see what
is happening there.
