[Qemu-devel] [PATCH 2/2] net: Don't use error_is_set() to suppress additional errors |

Using error_is_set(errp) that way can sweep programming errors under
the carpet when we get called incorrectly with an error set.
qmp_query_rx_filter() breaks its loop when it detects an error. It
needs to set another error when the loop completes normally.
Return right away instead of merely breaking the loop.
