    [ide] ide-tape: fix character device ->open() vs ->cleanup() race

    Similar to the same race but for the block device.

    * store pointer to struct ide_tape_obj in idetape_chrdevs[]
    * rename idetape_chrdevs[] to idetape_devs[] and kill idetape_chrdev_t
    * add ide_tape_chrdev_get() for getting reference to the tape
    * store tape pointer in file->private_data and fix all users of it
    * fix idetape_chrdev_{open,release}() to get/put reference to the tape

<bzolnier@trik.(none)> (05/03/18 1.2238)
    [ide] ide-scsi: add basic refcounting

    * pointers to a SCSI host and a drive are added to idescsi_scsi_t
    * pointer to the SCSI host is stored in disk->private_data
    * ide_scsi_{get,put}() is used to {get,put} reference to the SCSI host

added).

<bzolnier@trik.(none)> (05/03/18 1.2234)
    [ide] ide-cd: add basic refcounting

    * based on reference counting in drivers/scsi/{sd,sr}.c
    * fixes race between ->open() and ->cleanup() (ide_unregister_subdriver()
      tests for drive->usage != 0 but there is no protection against new
users)
    * struct kref and pointer to a drive are added to struct ide_cdrom_info
    * pointer to drive's struct ide_cdrom_info is stored in disk->private_data
    * ide_cd_{get,put}() is used to {get,put} reference to struct
ide_cdrom_info
    * ide_cd_release() is a release method for struct ide_cdrom_info

    [ide] make ide_generic_ioctl() take ide_drive_t * as an argument

    As a result disk->private_data can be used by device drivers now.
