staging: iio: resolver: ad2s1210: fix use before initialization

Browse source 
[ Upstream commit 7fe2d05cee46b1c4d9f1efaeab08cc31a0dfff60 ]

This fixes a use before initialization in ad2s1210_probe(). The
ad2s1210_setup_gpios() function uses st->sdev but it was being called
before this field was initialized.
