qemu-iotests: update 185 output

Browse Source 
Commit 4486e89c21 ("vl: introduce
vm_shutdown()") added a bdrv_drain_all() call.  As a side-effect of the
drain operation the block job iterates one more time than before.  The
185 output no longer matches and the test is failing now.

It may be possible to avoid the superfluous block job iteration, but
that type of patch is not suitable late in the QEMU 2.12 release cycle.

This patch simply updates the 185 output file.  The new behavior is
correct, just not optimal, so make the test pass again.
