scsi: target: perform t10_wwn ID initialisation in target_alloc_device()
Initialise the t10_wwn vendor, model and revision defaults when a device is
allocated instead of when it's enabled. This ensures that custom vendor or
model strings set prior to enablement are not later overwritten with
default values.
The TRANSPORT_FLAG_PASSTHROUGH conditional can be dropped for the following
reasons:
- target_core_pscsi overwrites the defaults in the
pscsi_configure_device() callback.
+ the contents is then only used for ConfigFS via
$pscsi_dev/statistics/scsi_lu/vend, etc.
- target_core_user doesn't touch the defaults, nor are they used for
anything outside of ConfigFS.
