vgsp: fix per-type VRAM type lookup and canonical FB-size encoding

The 708a3802 per-type VRAM change stripped an nvidia- prefix from
mdev->type->sysfs_name, but sysfs_name is the registered type name
verbatim; the mdev core only prefixes the type DIRECTORY with the parent
driver string. Every lookup failed, so all mdevs silently fell back to
512 MiB, nvidia-vgpu-turing-1g was unreachable and available_instances
capped at 1. Match sysfs_name directly in get_available,
show_description and mdev_create.

Also canonicalise the NV_PFB_PRI_MMU_LOCAL_MEMORY_RANGE encoder
(BAR0+0x100ce0) by stripping factors of two from MAG so 512 MiB encodes
0x19 again (1 GiB 0x1a, 2 GiB 0x1b) instead of the non-canonical 0x204.

Default-512M behaviour is now byte-equivalent to the known-good pre-VRAM
module except max_instances=2. Module sha256 cb1724d3.
