xen-pciback: fix up cleanup path when alloc fails
When allocating a pciback device fails, clear the private
field. This could lead to an use-after free, however
the 'really_probe' takes care of setting
dev_set_drvdata(dev, NULL) in its failure path (which we would
exercise if the ->probe function failed), so we we
are OK. However lets be defensive as the code can change.
Going forward we should clean up the pci_set_drvdata(dev, NULL)
in the various code-base. That will be for another day.
