[Qemu-devel] [PULL 34/38] dump: Drop pointless error_is_set(), DumpState member errp |

From: Markus Armbruster <address@hidden>
In qmp_dump_guest_memory(), the error must be clear on entry, and we
always bail out after setting it, directly or via dump_init().
Therefore, both error_is_set() are always false. Drop them.
DumpState member errp is now write-only. Drop it, too.
