Right now, bdrv_swap() on NBD BDSs results in a segmentation fault
pretty much all of the time. This series fixes this.
Note that this is not a common case, as bdrv_swap() is generally only
performed on root BDSs (there are exceptions, though) and NBD BDSs
normally have a format BDS above them. However, due to misconfiguration
(or maybe it is not even a misconfiguration, but just a strange
configuration) these cases may indeed occur.
For the iotest to succeed, this series relies on
"iotests: Specify format for qemu-nbd".
I took the second patch in this series from my other series
"block: Rework bdrv_close_all()" (which has 21 patches itself and
depends on 64 other patches, so making this series rely on that one
probably would not have been a very good idea).

iotests: Add "wait" functionality to _cleanup_qemu
iotests: Add test for drive-mirror with NBD target
