Ethan Tidmore dd6183e427 iio: adc: ad7768-1: Fix ERR_PTR dereference in ad7768_fill_scale_tbl 
The function iio_get_current_scan_type() can return an error pointer,
the return value scan_type is not checked for this and immediately
dereferenced which can cause a kernel panic.

Add check for IS_ERR() and propagate the error back.

Fixes: ff085189cb ("iio: adc: ad7768-1: add support for ADAQ776x-1 ADC Family")
Reported-by: kernel test robot <lkp@intel.com>
Reported-by: Dan Carpenter <error27@gmail.com>
