[bug] qvm-block -a twice

[Manz Tiha]

Bug, IMHO

1. add external hdd to daily appvm

~]$ qvm-block -a daily dom0:sde1

2. list the device
...
dom0:sde1 (data) 488 GiB (attached to 'daily' as 'xvdi')

3. mount at daily appvm

user ~]$ sudo mount /dev/xvdi /mnt

4. accidentaly add to daily vm again on dom0

~]$ qvm-block -a daily dom0:sde1
~]$ qvm-block
...
dom0:sde1 (data) 488 GiB (attached to 'daily' as 'xvdj')
..

there is double add to daily (appVM) with double device mount point, but
on daily (appVM) still mounted as /dev/xvdi , and we can mount again as /dev/xvdj

when delete on dom0

~]$ qvm-block -d dom0:sde1
~]$ qvm-block
...
dom0:sde1 (data) 488 GiB

but, on daily (appVM) still can access the mount point (rw mode) on /dev/xvdi
when do umount at daily (appVM) , umount successful
but on dom0 was not attached to any appVM

Thanks
