Case 265 need 4 devices to test RAID10, so we need 4 or more devices not 2.
And the deletable device check method is also wrong, the virtual devices in
the VMs which are drived by virtio are also not deletable(no delete entry
point), but it is not managed in the virtual directory in sysfs, so the current
method will make a mistake and thinks they are deletable. Fix it by check
the delete entry point. This fix method can also avoid the users use
partitions to run case 265.

Changelog v1 -> v2:
- drop the independent device check
- modify the deletable device check
- do not modify README
