net: dsa: Remove prepare phase for FDB
The prepare phase for FDB add is unneeded because most of DSA devices can have failures during bus transactions (SPI, I2C, etc.), thus, the prepare phase cannot guarantee success of the commit stage. The support for learning FDB through notification chain, which will be introduced in the following patches, will provide the ability to notify back the bridge about successful offload.
