In r321967 ngie "fixed" these tests by changing their expectations to match
the device numbers produced by the new ino64 code. But it wasn't the tests
that were broken, it was the kernel. bde fixed the kernel in r335053.

The layout of st_rdev has changed after this commit, and assumptions made
in the NetBSD tests are no longer valid. Change the hardcoded assumed
values to account for the fact that major/minor are now represented by
64 bits as opposed to the less precise legacy precision of 16 bits.

Relnotes: st_rdev layout changed; warning about impact of r321920 to
downstream consumers
The previous logic was flawed in the sense that it assumed that /dev/md3
was always available. This was a caveat I noted in r306038, that I hadn't
gotten around to solving before now.
Cache the device for the mountpoint after executing mdmfs, then use the
cached value in basic_cleanup(..) when unmounting/disconnecting the md(4)
device.
Apply sed expressions to use reuse logic in the NetBSD code that could
also be applied to FreeBSD, just with different tools.
