[PATCH v8 4/4] net/bnxt: notify applications about device reset/recovery

[Chengwen Feng]

From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

When the driver receives RESET_NOTIFY async event from FW or detects
an error condition, it should update the application that FW is going
to reset. Once the driver recovers from the reset, update the reset
recovery status to application as well.
