Use the new GlobalProperty.errp field to handle compat_props
errors.

Example output before this change:
(with an intentionally broken entry added to PC_COMPAT_1_3 just
for testing)

   $ qemu-system-x86_64 -machine pc-1.3
   qemu-system-x86_64: hw/core/qdev-properties.c:1091: 
qdev_prop_set_globals_for_type: Assertion `prop->user_provided' failed.
   Aborted (core dumped)

After:

   $ qemu-system-x86_64 -machine pc-1.3
   Unexpected error in x86_cpuid_set_vendor() at 
/home/ehabkost/rh/proj/virt/qemu/target-i386/cpu.c:1688:
