libxl: avoid blktap2 deadlock on cleanup
Establishes correct cleanup behavior for blktap devices. This patch
implements the release of the backend device before calling for
the destruction of the userspace component of the blktap device.
Without this patch the kernel xen-blkback driver deadlocks with
the blktap2 user control plane until the IPC channel is terminated by the
timeout on the select() call. This results in a noticeable delay
in the termination of the guest and causes the blktap minor
number which had been allocated to be orphaned.
