fix(components/adc) unexpected abort

label `cleanup` redirect to adc_continuous_deinit() ->
-> adc_apb_periph_free() -- and call unexpected decrement and abort. but
the increment of s_adc_digi_ctrlr_cnt was not made. also abort does not
allow us to understand what the error was (return is not provided)
