[PATCH for-6.0 v2 2/2] hw/block/nvme: disable hotplugging for subsystem-linked controllers

[Klaus Jensen <its@irrelevant.dk>]

From: Klaus Jensen <k.jensen@samsung.com>

If a controller is linked to a subsystem, do not allow it to be
hotplugged since this will mess up the (possibly shared) namespaces.
