Subject: [PATCH 5.7 100/124] Revert "scsi: qla2xxx: Disable T10-DIF feature with FC-NVMe during probe"

From: Quinn Tran <qutran@...vell.com>

[ Upstream commit dca93232b361d260413933903cd4bdbd92ebcc7f ]

FCP T10-PI and NVMe features are independent of each other. This patch
allows both features to co-exist.

This reverts commit 5da05a26b8305a625bc9d537671b981795b46dab.
