hv: vmbus_free_channels(): remove the redundant free_channel()

Browse source

free_channel() has been invoked in
vmbus_remove() -> hv_process_channel_removal(), or vmbus_remove() ->
... -> vmbus_close_internal() -> hv_process_channel_removal().

We also change to use list_for_each_entry_safe(), because the entry
is removed in hv_process_channel_removal().

This patch fixes a bug in the vmbus unload path.

Thank Dan Carpenter for finding the issue!
