The function scsi_bus_new() creates a new SCSI bus; callers can
either pass in a name argument to specify the name of the new bus, or
they can pass in NULL to allow the bus to be given an automatically
generated unique name. Almost all callers want to use the
autogenerated name; the only exception is the virtio-scsi device.
Taking a name argument that should almost always be NULL is an
easy-to-misuse API design -- it encourages callers to think perhaps
they should pass in some standard name like "scsi" or "scsi-bus". We
don't do this anywhere for SCSI, but we do (incorrectly) do it for
other bus types such as i2c.
The function name also implies that it will return a newly allocated
object, when it in fact does in-place allocation. We more commonly
name such functions foo_init(), with foo_new() being the
allocate-and-return variant.
Replace all the scsi_bus_new() callsites with either:
* scsi_bus_init() for the usual case where the caller wants
an autogenerated bus name
* scsi_bus_init_named() for the rare case where the caller
needs to specify the bus name
and document that for the _named() version it's then the caller's
responsibility to think about uniqueness of bus names.

Rename ipack_bus_new_inplace() to ipack_bus_init(), to bring it in to
line with a "_init for in-place init, _new for allocate-and-return"
convention. Drop the 'name' argument, because the only caller does
not pass in a name. If a future caller does need to specify the bus
name, we should create an ipack_bus_init_named() function at that
point.

Rename the pci_root_bus_new_inplace() function to
pci_root_bus_init(); this brings the bus type in to line with a
"_init for in-place init, _new for allocate-and-return" convention.
To do this we need to rename the implementation-internal function
that was using the pci_root_bus_init() name to
pci_root_bus_internal_init().

I have not attempted to tackle a possible _named vs not
split here because a lot of callsites specify a name when
they arguably should not.

Rename qbus_create_inplace() to qbus_init(); this is more in line
with our usual naming convention for functions that in-place
initialize objects.
