xilinx: Fix latent error handling bug
Assigning directly to *errp is not valid, as errp may be null,
&error_fatal, or &error_abort. The !*errp conditional protects
against the latter two, but we then leak @local_err. Fortunately,
the qdev core always passes pointer to null, so this is "merely" a
latent bug.
Use error_propagate() instead.
