iio: chemical: bme680: Fix measurement wait duration calculation

Browse source

commit f55b9510cd upstream.

This function refers to the Bosch BME680 API as the source of the
calculation, but one of the constants does not match the Bosch
implementation. This appears to be a simple transposition of two digits,
resulting in a wait time that is too short. This can cause the following
'device measurement cycle incomplete' check to occasionally fail, returning
EBUSY to user space.

Adjust the constant to match the Bosch implementation and resolve the EBUSY
errors.
