msm-camera: sensor: Fixing kernel crash during i2c read

When userspace uses ioctl(), kernel should get the data from
userpsace through copy_from_user() or get_user() and send it
back to userpsace though copy_to_user() or put_user().
In this case, kernel is not using put_user or copy_to_user
which is leading to a crash during I2C read when it tries to
access memory.
