Now that the PIIX IDE device models check for presence of an ISABus before
using it, this fix isn't needed any longer.
This reverts commit 9405d87be25db6dff4d7b5ab48a81bbf6d083e47.

This series resolves the global "isabus" variable and is basically a v2 of [1].

which implicitly rely on the usage of the isabus global.

This should fix the last caller causing a NULL ISADev to be passed to

The next patch will introduce a quirk for user-created PIIX IDE devices for

Coverity reported a string overflow issue since we copied
"name" to "dev_config->name" without checking the length.
This should be a false positive since we already checked
the length of "name" in vduse_name_is_invalid(). But anyway,
let's replace strcpy() with strncpy() to fix the coverity

In vduse_name_is_valid(), we actually check whether
the name is invalid or not. So let's change the
function name to vduse_name_is_invalid() to match
the behavior.

The serial prop on the controller is actually describing the nvme

the same nvme subsystem.

Command handlers shouldn't send replies themselves, but just prepare the
message and let vu_dispatch() send it. Otherwise, vu_dispatch() will add
a second reply as an ACK when NEED_REPLY was requested.
