feat(LargeBlock): add error for multidevices (#53)

Add an error to explicitly say that multi devices SR is not supported on the driver. Before that, it would make another error: ``` Error code: SR_BACKEND_FAILURE_77 Error parameters: , Logical Volume group creation failed, ``` Signed-off-by: Damien Thenot <[email protected]>
