xen/pt: Fix incomplete conversion to realize()

The conversion of "xen-pci-passthrough" to realize() (commit
5a11d0f7549, v2.6.0) neglected to convert the xen_pt_config_init()
error path.  If xen_pt_config_init() fails, xen_pt_realize() reports
the error, then returns success without completing its job.  I don't
know the exact impact, but it can't be good.

Belatedly convert the error path.
