ceph-volume: fix raw list with logical partition

This is a regression introduced by 9212420, when the host is using a
logical partition then lsblk reports that partition as a child from the
physical device.
That logical partition is prefixed by the `└─` character.

This leads the `raw list` subcommand to show the lsblk error on the stderr.

```
$ ceph-volume raw list
{}
 stderr: lsblk: `-/dev/sda1: not a block device
```

The lsblk command output looks like:

```
$ lsblk --paths --output=NAME --noheadings
/dev/sda
└─/dev/sda1
/dev/sdb
/dev/sdc
/dev/sdd
```

Using the `--list` option with lsblk solves the issue.

```
$ lsblk --list --paths --output=NAME --noheadings
/dev/sda
/dev/sda1
/dev/sdb

librbd/cache/pwl: don't clear next_sync_point_entry prematurely

In SyncPointLogOperation::clear_earlier_sync_point(),
sync_point->log_entry->next_sync_point_entry was prematurely set to
nullptr in clear_earlier_sync_point(). It is in write op stage, but
next_sync_point_entry is used in writeback stage in
handle_flushed_sync_point().

handle_flushed_sync_point() may pass a nullptr
cause assert in m_work_queue.The solution is to move the statement
that set next_sync_point_entry to nullptr after it is used.
