net: stmmac: Drop useless code related to ethtool rx-copybreak

Browse source

After commit 2af6106ae9 ("net: stmmac: Introducing support for Page
Pool"), the driver always copies frames to get a better performance,
zero-copy for RX frames is no more, then these code turned to be
useless and users of ethtool may get confused about the unhandled
rx-copybreak parameter.

This patch mostly reverts
commit 22ad383815 ("stmmac: do not perform zero-copy for rx frames")
