Fix PCI device attach in xend driver
When attaching PCI device using the xend driver, the 'device_create'
RPC is called, which is not sufficient to fully prepare/configure
the device for attachment to a domain. In the xen tools, xm pci-attach
uses the 'device_configure' RPC.
This patch changes the xend driver to always call 'device_configure' for
PCI devices to be consistent with the usage in the xen tools.
