Fixes gcc '-Wunused-but-set-variable' warning:

drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_shub.c: In function 'st_lsm6dsx_shub_read_reg':
drivers/iio/imu/st_lsm6dsx/st_lsm6dsx_shub.c:108:41: warning:
variable 'hub_settings' set but not used [-Wunused-but-set-variable]

It never used since introduction in commit c91c1c844ebd ("iio: imu: st_lsm6dsx:
add i2c embedded controller support")
