[PATCH v2] x86: Dom0 "broken ELF" reporting adjustments

[Jan Beulich <jbeulich@xxxxxxxx>]

elf_load_binary() isn't the primary source of brokenness being
indicated. Therefore make the respective PVH log message there
conditional (much like PV has it), and add another instance when
elf_xen_parse() failed (again matching behavior in the PV case).

Make the PV side match the (new) use of %pd here.

v2: Use %pd and bring PV in line with that as well.
