realtek: cleanup rtl83{8x,9x}_enable_learning/flood
In *_enable_learning() only address learning should be configured, so
remove enabling forwarding. Forwarding is configured by the respective
*_enable_flood() functions.
Clean up both functions for RTL838x and RTL839x, and fix the comment on
the number of entries.
