iio: adc: ad_sigma_delta: Fix use of uninitialized status_pos
Fix Smatch-detected issue:
drivers/iio/adc/ad_sigma_delta.c:604 ad_sd_trigger_handler() error:
uninitialized symbol 'status_pos'.
The variable `status_pos` was only initialized in specific switch cases
(1, 2, 3, 4), which could leave it uninitialized if `reg_size` had an
unexpected value.
Fix by adding a default case to the switch block to catch unexpected
values of `reg_size`. Use `dev_err_ratelimited()` for error logging and
`goto irq_handled` instead of returning early.
