fix(adc): add missing input validation for channel and ret_handle

Browse Source 
- adc_cali_curve_fitting: validate config->chan in check_valid() to
  prevent OOB access into s_adc_cali_chan_compens compensation table
- adc_filter: make s_adc_filter_free idempotent on !UNIT_BINDED SoCs
  to prevent double-free on repeated adc_del_continuous_iir_filter
- adc_cali_line_fitting(esp32): fix config && config typo to
  config && ret_handle, preventing NULL-pointer dereference
