[PATCH v3 1/4] iotests/nbd-in-qcow2-chain: use default machine

[Eric Farman <farman@linux.ibm.com>]

Some of the NBD tests explicitly specify `-machine q35` which won't work
when running against, say, qemu-system-s390x.

The nbd-in-qcow2-chain test runs fine with the default machine on a z16
host, so allow it to run in other configurations.

Fixes: 24fd6d75b3 ("iotests: Add coverage of recent NBD qio deadlock fix")
Signed-off-by: Eric Farman <farman@linux.ibm.com>
