e1000e: release hw semaphore after successfully writing EEPROM

Since e1000e has been existance in linux-2.6, we've
never released the hardware semaphore after a successful
write to the SPI EEPROM.  I guess we don't write to
SPI EEPROM much -- but those few of us that do appreciate
it when we can later read from the EEPROM without having
to reboot.
