[PATCH] libxl: Fix node device detach when driver unspecified
Commit 887dd0d331 caused a small regression in NodeDeviceDetach in the libxl
driver when the 'driver' parameter is not specified. E.g.
error: Failed to detach device pci_0000_0a_10_0
error: An error occurred, but the cause is unknown
If the driver name is not specified, NULL is passed to
virDomainDriverNodeDeviceDetachFlags, in which case virPCIDeviceSetStubDriver
is never called to set the stub to pciback. Fix it by setting the driver to
"xen" if it is not specified when invoking NodeDeviceDetach.
