[dpdk-stable] [PATCH 04/22] net/bnxt: fix an unconditional wait in link update

[Ajit Khaparde]

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

There is an unconditional delay in link update op.
Fixed it to wait only if wait for request completion is set.

Fixes: 7bc8e9a227ccbc64 ("net/bnxt: support async link notification")
