vm_tools: Fix crash in ~VmExportOperation

The default destructor would delete the memory containing a hash of
the data written so far before destroying the object representing the
write operation. This could cause a crash if the destruction occurred
in the middle of the operation, because cancelling it would trigger
callbacks that expected to be able to access the hash. Fix this by
adding an explicit destructor that triggers these callbacks before
deleting anything else.
