Subject: [PATCH] power/ds2782: fix clientdata on removal

Probably due to a copy & paste bug, clientdata was set again to the data
structure (which is freed immediately afterwards) when it should be
NULLed. Just remove the calls as the i2c-core does this automatically
now.

Anton: If it is okay with you, I think this should go via the I2C-tree to
ensure it comes after the needed modification of the i2c-core.
