[PATCH] be2net: Remove code that stops further access to BE NIC based on UE bits

[Ajit Khaparde <ajit.khaparde@emulex.com>]

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.
