findmnt: properly exclude poll columns from --output-all

Previously columns excluded from --output-all where in fact stored as
column index 0. This however is COL_ACTION which is a polled column
leading to the following error:

findmnt --output-all
findmnt: ACTION column is requested, but --poll is not enabled
