net/mlx5e: Fix minimum MTU

Browse source

[ Upstream commit d8edd2469a ]

Minimum MTU that can be set in Connectx4 device is 68.

This fixes the case where a user wants to set invalid MTU,
the driver will fail to satisfy this request and the interface
will stay down.

It is better to report an error and continue working with old
mtu.
