block: move holder_dir from disk to part0
Move disk->holder_dir to part0->holder_dir. Kill now mostly
superflous bdev_get_holder().
While at it, kill superflous kobject_get/put() around holder_dir,
slave_dir and cmd_filter creation and collapse
disk_sysfs_add_subdirs() into register_disk(). These serve no purpose
but obfuscating the code.
