fix(v4.0.0): three defects -- a refused device write, a failed starting state, a case that QUITs

A block write the device refuses after the kernel has taken the node's
copy: the node was told "Storage refused" while the kernel's cache kept
the new data, to be read back and perhaps written later.  The kernel now
puts its own copy back as it was.  Tested with a device whose writes can
be made to fail; it failed first.

POST's runner: a case whose starting state could not be set says so, with
what the node said, where it showed nothing; and a case that ends with
QUIT fails, as it did when the cases were a capsule, where the runner had
taken it for a completed line.  Both tests failed first.

The v4 boot says "Artemis: virtio-blk attached" only when the attach
worked.

make -C v4 test, sanitize and hosted-check pass; amd64, aarch64 and
riscv64 boot, POST 538 of 538, dict_hash 0x5f0a949a6fc8ef2b on all six:
