i2c: dev: Force case user pointers in compat_i2cdev_ioctl() ...
Sparse has warned us about wrong address space for user pointers:
i2c-dev.c:561:50: warning: incorrect type in initializer (different address spaces)
i2c-dev.c:561:50: expected unsigned char [usertype] *buf
i2c-dev.c:561:50: got void [noderef] __user *
Force cast the pointer to (__u8 *) that is used by I²C core code.
Note, this is an additional fix to the previously addressed similar issue
in the I2C_RDWR case in the same function.
