[PATCH] i2c: Remove obsolete cleanup for clientdata

[Wolfram Sang <w.sang-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>]

A few new i2c-drivers came into the kernel which clear the clientdata-pointer
on exit. This is obsolete meanwhile, so fix it and hope the word will spread.

Like last time I suggest to collect acks from the driver authors and merge it
vie Jean's i2c-tree.
