Fix stm32 eeprom handling (#205)

Browse Source 
* Update stm32_platform.cpp

Addresses a side effect of https://github.com/thelsing/knx/pull/177, which causes the eeprom buffer to be overwritten every time getEepromBuffer is called. This prevented programming of STM32 boards as their initial bus address was lost before programming.

* Code style fix
