I don't want to change all of the functions.  For most devices, there's no
way I can test them.

Just because pci_eth_int() is incorrect, that doesn't mean that I can't make
tsec_eth_init() correct.

What's the point of making the return value a signed integer if it can never
be a negative number?  The reason I changed the type to unsigned int is to
make it very clear that it will never return an error code.
