Subject: i2c: mux: pca954x: retry updating the mux selection on failure

From: Peter Rosin <[email protected]>

commit 463e8f845cbf1c01e4cc8aeef1703212991d8e1e upstream.

The cached value of the last selected channel prevents retries on the next call, even on failure to update the selected channel. Fix that.
