be2net: Remove code that stops further access to BE NIC based on UE bits
On certain platforms, BE hardware could falsely indicate UE.
For BE family of NICs, do not set hw_error based on the UE bits.
If there was a real fatal error, the corresponding h/w block will
automatically go offline and stop traffic.
