Hi All,

We tested the xm block-attach/detach command.
It repeats block-attach/detach command for DomU and pv-on-hvm on HVM Domain.
(block-attach -> block-detach -> block-attach -> block-detach -> ...)

The block-attach command failed when repeating 256 times. It is because the channel had not been freed in blkfront. Therefore, it remain using the event channel. This patch is corrected to free the event channel in blkfront.
Thanks
