ide: add support for SCSI ioctls to ide-floppy
Now that ide-floppy supports SG_IO we can add support for SCSI ioctls
(except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET
ones - we can add them later iff really needed).
While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from
generic_ide_ioctl():
- This prevents ide-{disk,tape,scsi} device drivers from obtaining
REQ_TYPE_BLOCK_PC type requests which are currently unsupported by
these drivers and which are potentially harmful (as reported by Andrew).
- There is no functionality loss since aforementioned ioctls will now be
handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using
ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl()
(for devices using ide-cd driver).
