i386/kvm/pci-assign: Use errp directly rather than local_err
In assigned_device_pci_cap_init(), first, error messages are filled
to a local_err variable, then through error_propagate() pass to
the parameter of errp. It leads to cumbersome code. In order to
avoid the extra local_err and error_propagate(), drop it and use
errp instead.
