[dpdk-stable] [PATCH 19.11 3/6] net/bnxt: invoke device removal event on recovery failure

[Kalesh A P]

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

[ upstream commit 8ac3cbba621ad1887b069b271115faf76bf04b75 ]

When the driver receives RESET_NOTIFY async event from FW or detects
a FW fatal error condition, it tries to recover from the error.
When the driver fails to recover from the error condition, fixed to
send device removal event to the application.

Fixes: df6cd7c1f73a ("net/bnxt: handle reset notify async event from FW")
