Subject: [PATCH 4.19 143/245] scsi: qedi: Fix termination timeouts in session logout

From: Nilesh Javali <njavali@...vell.com>

[ Upstream commit b9b97e6903032ec56e6dcbe137a9819b74a17fea ]

The destroy connection ramrod timed out during session logout.  Fix the
wait delay for graceful vs abortive termination as per the FW requirements.
