QSerialPortInfo FreeBSD: improve error handling in OID parsing

The sysctl() call can theoretically return a zero length or a length
that does not represent a whole amount of ints. In such case, the next
sysctl() would have accessed the first element of an empty array or
passed an incorrect length due to truncating. In both cases that could
lead to accessing the memory past the end of the allocated QList.

Note that it is unlikely to happen in practice, unless there's a bug
in the kernel, because on success at least one component should be
available.

Still, adding these guards won't hurt. But I'm not picking this patch
to ESM branches.

QSerialPortInfo FreeBSD: assert the preconditions in a helper function

The fact that previousOid should not be empty is a precondition for
the nextOid() helper function. This is currently checked at the call
sites. Add a Q_ASSERT() to guarantee that a future refactoring does
not skip the condition.

QSerialPort docs: clarify negative values in set{Read,Write}BufferSize

Generally speaking, passing negative value as a buffer size does not
make sense. However, in practice negative parameters are handled
differently for read and write buffers.
Document it to avoid confusion.

QSerialPortInfo FreeBSD: avoid variable shadowing

The availablePorts() implementation has two loops over nodes, where
the second one shadows the outer variable:

  for (const NodeInfo &node : nodes) {
    // ...
    for (const NodeInfo &node : nodes) {
      // ...
    }
  }

Rename the inner variable to descriptionNode, because it's used to
populate the device description and manufacturer information.
