Subject: [PATCH net-next v2 3/6] bnxt_en: Don't call ULP_STOP/ULP_START during L2 reset

There is no need to call ULP_STOP and ULP_START before and after the
L2 reset in bnxt_reset_task().  This L2 reset is done after detecting
TX timeout, RX ring errors, or VF config changes.  The L2 reset does
not affect RoCE since the firmware is not reset and the backing store
is left alone.
