bnx2: reset_task is crashing the kernel. Fixing it.

Browse source 
If bnx2 schedules a reset via the reset_task, e.g., due to a TX
timeout, it's possible for the NIC to be disabled with packets
pending for transmit.  In this case, napi_disable will loop forever,
eventually crashing the kernel.  This patch moves the disable of
the device to after the napi_disable call.
