Subject: [PATCH 5.16 142/186] ibmvnic: complete init_done on transport events

From: Sukadev Bhattiprolu <sukadev@...ux.ibm.com>

[ Upstream commit 36491f2df9ad2501e5a4ec25d3d95d72bafd2781 ]

If we get a transport event, set the error and mark the init as
complete so the attempt to send crq-init or login fail sooner
rather than wait for the timeout.

Fixes: bbd669a868bb ("ibmvnic: Fix completion structure initialization")
