[PATCH v2 06/15] qemuMonitorJSONHandleIOError: Propagate new 'qom-path' field

[Peter Krempa <pkrempa@xxxxxxxxxx>]

QEMU commit v9.1.0-1065-ge67b7aef7c added 'qom-path' as an optional
field for the BLOCK_IO_ERROR event. Extract and propagate it as an
alternative to lookup via 'node-name' and 'device' (alias).
