xenapi: don't send terminating chunk on errors

Browse Source 
If we send the terminator on an error, it looks like we have actually
completed the upload, when that was not actually the case, we have
failed, and ideally we want glance to notice and mark the snapshot as
failed.

This partly reverts the following commit:
e039b036b5

It is not a full revert of the above commit, and some of the refactoring
and error handling changes are still useful.
