[PATCH 5.14 089/162] atlantic: Fix issue in the pm resume flow.

[Greg Kroah-Hartman]

From: Sudarsana Reddy Kalluru <skalluru@xxxxxxxxxxx>

[ Upstream commit 4d88c339c423eefe2fd48215016cb0c75fcb4c4d ]

After fixing hibernation resume flow, another usecase was found which
should be explicitly handled - resume when device is in "down" state.
Invoke aq_nic_init jointly with aq_nic_start only if ndev was already
up during suspend/hibernate. We still need to perform nic_deinit() if
caller requests for it, to handle the freeze/resume scenarios.

Fixes: 57f780f1c433 ("atlantic: Fix driver resume flow.")
