[PATCH] iio: imu: kmx61: fix simple_return.cocci warnings

[kbuild test robot <fengguang.wu@intel.com>]

drivers/iio/imu/kmx61.c:543:1-4: WARNING: end returns can be simpified
drivers/iio/imu/kmx61.c:480:1-4: WARNING: end returns can be simpified if negative or 0 value

 Simplify a trivial if-return sequence.  Possibly combine with a
 preceding function call.
