1. Bug fix for error: "Error: Device /dev/xvdp (51952, tap2) is already connected."
2. Bug fix for error: "Error: Device 51952 not connected" 


process of booting DomU with 'mounted-blktap2' (VHD for example) and 'pygrub' as bootloader:

1. Connect boot-device to Dom0 as '/dev/xpvd'
2. Pygrub get info for load DomU
3. Disconnect boot-device from Dom0
4. Boot DomU

During step 3 created device disconnecting from Dom0, but xenstore does not scrape away after device disconnected from Dom0 => result: 
    "Error: Device /dev/xvdp (51952, tap2) is already connected."

During step 3 created device disconnecting from Dom0, but 'destroyDevice' method is passed 'tap' always => result:
    "Error: Device 51952 not connected"
