[PATCH] I2C: refactor message in i2c_detach_client
We could refactor the error message 34 different i2c drivers print if
i2c_detach_client() fails in this function itself. Saves quite a few
lines of code. Documentation is updated to reflect that change.
Note that this patch should be applied after Rudolf Marek's w83792d
patches.
