Some tests require the scratch volume to be a block device,
although they don't do anything block device specific like
the device mapper tests. They actually only require a local
device and fail with network or overlay pseudo mount devices.
The same tests also try to mount the scratch device manually
after running _scratch_mkfs. For UBIFS, _scratch_mkfs simply
truncates the UBI volume and relies on the kernel to re-format
the volume on the next mount. This fails if the fs type is not
specified explicitly when mounting.
This patch replaces the block device requirement with a
generic check for a local device and adds a filesystem
specification to all manual mounts of the scratch device
to a mount point.

After some shared subtrees test (bind/slave/shared/private), maybe
some dentries isn't freed. For example, EBUSY maybe returned due to
some bugs. This patch tries to verify that.

This test cover linux commit 7ae8fd0, when mnt_group_id=0, it means
this mount no peers. But this bug treat two zero mnt_group_id as
peers. And it cause a crash by dereference a NULL address.
As below, the crash will happen when mount fs on "B/mnt1/mnt2":
shared New FS shared
-----------------------[A/mnt1]----------------------
| | |
| bind | bind |
[C/mnt1]--[slave C]<------[shared A]------>[slave B]--[B/mnt1]
|
|
[B/mnt1/mnt2]
(New FS)
