iio: imu: st_lsm6dsx: fix waitime for st_lsm6dsx i2c controller
[ Upstream commit fdb828e2c71a09bb9e865f41b015597c5f671705 ]
i2c controller available in st_lsm6dsx series performs i2c slave
configuration using accel clock as trigger.
st_lsm6dsx_shub_wait_complete routine is used to wait the controller has
carried out the requested configuration. However if the accel sensor is not
enabled we should not use its configured odr to estimate a proper timeout
Fixes: c91c1c844ebd ("iio: imu: st_lsm6dsx: add i2c embedded controller support")
