[Qemu-devel] [PULL 5/9] migration: unify error handling for process_incoming_migration_co |

From: Fei Li <address@hidden>
In the current code, if process_incoming_migration_co() fails we do
the same error handing: set the error state, close the source file,
do the cleanup for multifd, and then exit(EXIT_FAILURE). To make the
code clearer, add a "goto fail" to unify the error handling.
