Martin Roth 681284ca22 npcx/i2c.c: Verify that controller value is not negative before using it ...

The function i2c_port_to_controller() returns a negative value if
the port value was out of range.  This wasn't being checked before the
controller value was getting used which could lead to using an invalid
value as a pointer to a structure.

This returns an error where it makes sense, and just ignores the
incorrect value otherwise.
