sunvdc: don't call VD_OP_GET_VTOC

The VD_OP_GET_VTOC operation will succeed only if the vdisk backend has a
VTOC label, otherwise it will fail. In particular, it will return error
48 (ENOTSUP) if the disk has an EFI label. VTOC disk labels are already
handled by directly reading the disk in block/partitions/sun.c (enabled by
CONFIG_SUN_PARTITION which defaults to y on SPARC). Since port->label is
unused in the driver, remove the call and the field.

Pull sparc update from David Miller:
 "Two changes:

  1) It makes no sense to execute a VTOC partition table request in the
     Sun virtual block device driver and fail to load if it doesn't
     succeed because a) we don't use the result at all and b) it won't
     succeed if there is an EFI partition on the disk, for example.

     We read the partition table via the normal means in the block layer
     anyways, so this is really completely useless, so just remove it.

     From Dwight Engen.

  2) Hook up new bpf system call"
