qemu: block: Remove 'active-write' bitmap even if there are no bitmaps to merge The 'libvirt-tmp-activewrite' bitmap is added during the 'pivot' operation of block copy and active layer block commit operations regardless of whether there are any bitmaps to merge, but was not removed unless a bitmap was merged. This meant that subsequent attempts to merge into the same image would fail. Fix it by checking whether the 'libvirt-tmp-activewrite' would be used by the code and don't skip the code which would delete it. This is a regression introduced when we switched to the new code for block commit in <20a7abc2d2d> and for block copy in <7bfff40fdfe5>. The actual bug originates from <4fa8654ece>. https://bugzilla.redhat.com/show_bug.cgi?id=1857735 Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> 2020-07-16 12:46:43 +00:00			`[`
