[PATCH] posix-clock: Remove duplicate ioctl handler

[Thomas Weißschuh]

The normal and compat ioctl handlers are identical,
which is fine as compat ioctls are detected and handled dynamically [0].
The duplicate definition however is unnecessary.
Just reuse the regular ioctl handler also for compat ioctls.
