[PATCH v2] staging: iio: ad5933: fix order of cycle conditions

[Luis de Bethencourt]

Correctly handle the settling time cycles value. The else branch is an
impossible condition, > 1022 in the else branch of > 511. Flipping the order.

Based on the Table 13 at the bottom of Page 25 of the Data Sheet:
