[dpdk-stable] [PATCH 19.11 3/3] net/bnxt: remove a redundant variable

[Kalesh A P]

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

[ upstream commit 90c957ef3b11f361dd8e6519d9e195f01295b23e ]

Use "dev->data->dev_started" state, instead of local "dev_stopped"
to check whether port has been started or not.

Fixes: 316e412299fd ("net/bnxt: fix crash when closing")
