Markus Armbruster April 29, 2020, 7:20 a.m. UTC 
The conversion of xen_pt_initfn() to xen_pt_realize() blindly replaced
XEN_PT_ERR() by error_setg().  Several error conditions that did not
fail xen_pt_initfn() now fail xen_pt_realize().  Unsurprisingly, the
cleanup on these errors looks highly suspicious.

Revert the inappropriate replacements.
