Do not force VDEV_NAME_TYPE_ID in max_width() 

Do not force VDEV_NAME_TYPE_ID in max_width(), instead add it
in the relevant calls to max_width().

The first location of max_width() where VDEV_NAME_TYPE_ID is
now added in show_import() is followed by print_import_config() and
print_logs().  Both these print children vdev names that have been
retrieved using an explicit VDEV_NAME_TYPE_ID added.

The second location is in status_callback().  This is followed by
print_status_config(), print_logs(), print_l2cache(), and
print_spares(). For l2cache and spares it should not matter as there
are no mirror-X or raidz-X involved.  print_status_config() as above
retrieves the name using explicit VDEV_NAME_TYPE_ID before
calling itself to print children.

The call of max_width() in get_namewidth() is not changed, as this is
used by zpool_do_iostat(), followed by print_iostat(), which does not
add VDEV_NAME_TYPE_ID.

Overall, we should consider adding VDEV_NAME_TYPE_ID to the
relevant name_flags / cb_name_flags fields, and remove the explicit
adding in called routines.
