In newer versions of the kernel, there is a race condition that causes
the kernel block layer to mess up if an nvme-oF subsystem is
disconnected before it is fully removed. This can cause the shutdown
test to hang during a sync call aftr nvmf tgt shutdown. see:
d1ecb02290.1537982067/fedora-06/build.log
for details.
This problem has been observed and fixed in the RPC tests also.
