qom: Don't keep error value between object_property_parse() calls
When handling errp==NULL at object_apply_global_props(), we are leaving the old error value in `err` after printing a warning. This makes QEMU crash if two global properties generate warnings: $ echo device_add rtl8139 | qemu-system-x86_64 -monitor stdio -global rtl8139.xxx=yyy -global rtl8139.xxx=zzz warning: can't apply global rtl8139.xxx=yyy: Property '.xxx' not found qemu-system-x86_64: util/error.c:57: error_setv: Assertion `*errp == NULL' failed. Aborted (core dumped) Fix that by making `err` go out of scope immediately after the warn_report_err() call.
