net/mlx4_en: Change min MTU size to ETH_MIN_MTU
[ Upstream commit 24be19e47779d604d1492c114459dca9a92acf78 ]
NIC driver minimal MTU size shall be set to ETH_MIN_MTU, as defined in
the RFC791 and in the network stack. Remove old mlx4_en only define for
it, which was set to wrong value.
Fixes: b80f71f5816f ("ethernet/mellanox: use core min/max MTU checking")
