The LOAD_DISPLAY (LDD) X'9F' is still accepted by the Virtual Tape
Server (VTS) but does not perform any action.
Remove all functions and definitions related to this command.
The tape_34xx_ioctl() function is also removed as it was mainly used to
handle additional ioctl functionality. LOAD_DISPLAY was the only left
case. All other ioctls are handled in tapechar_ioctl().
With LOAD_DISPLAY, the remaining definitions in asm/tape390.h are gone.
Delete the file.
