Subject: [PATCH] mkdumprd (RHEL-only): add nvme module by force

Resolves: bz2017121
Upstream: RHEL-only

The following dracut commit can not detect the nvme module in some special
case, which causes vmcore dump failure.

commit c86f4d286000d1e76fd405560b4114537e2cbbff
Author: Pingfan Liu <piliu@redhat.com>
Date:   Wed Jul 28 18:13:43 2021 +0800

    fix(kernel-modules): detect block device's hardware driver

As a workaround, adding nvme module by force at present, and after a
real fix in dracut, we can revert this patch.
