Yong Tang f5d346298d Run btrfs rescan only if userDiskQuota is enabled ...

This fix tries to address the issue raised in 29810
where btrfs subvolume removal failed when docker
is in an unprivileged lxc container. The failure
was caused by `Failed to rescan btrfs quota` with
`operation not permitted`.

However, if disk quota is not enabled, there is no
need to run a btrfs rescan at the first place.

This fix checks for `quotaEnabled` and only run btrfs
rescan if `quotaEnabled` is true.

This fix fixes 29810.
