Just to comply with the data sheet, explicitly set the JTAG pins to pull-down when reset.
Addresses #5787
Tested on cm4io and pi4b -- has no apparent impact. Worked before and after.

whoops -- there is a logic flaw -- I need to remove the return and let the other if/else set it to Pull-down
I'll fix, retests and update

fixed and rested on cm4io and pi4b -- still seems to "do no harm"

The following fixes are made:
- cancelling a gather now cancels all sub-tasks of the gather (previously
  it would only cancel the first)
- if any sub-task of a gather raises an exception then the gather finishes
  (previously it would only finish if the first sub-task raised)

Fixes issues adafruit#5798, adafruit#7807, adafruit#7901.
