vfio/common: Abort migration if dirty log start/stop/sync fails
If VFIO dirty pages log start/stop/sync fails during migration,
migration should be aborted as pages dirtied by VFIO devices might not
be reported properly.
This is not the case today, where in such scenario only an error is
printed.
Fix it by aborting migration in the above scenario.
Fixes: 758b96b61d5c ("vfio/migrate: Move switch of dirty tracking into vfio_memory_listener")
Fixes: b6dd6504e303 ("vfio: Add vfio_listener_log_sync to mark dirty pages")
Fixes: 9e7b0442f23a ("vfio: Add ioctl to get dirty pages bitmap during dma unmap")
