qemuDomainBlockPivot: Ignore failures of creating active layer bitmap

Ignore errors from creating "libvirt-tmp-activewrite" bitmap. This
prevents failures of finishing blockjobs if the bitmap already exists.

Note that if the bitmap exists, the worst case that can happen is that
more bits are marked as dirty in the resulting merge.
