can: proc: make array printing function indenpendent from sff frames

The can_rcvlist_sff_proc_show_one() function which prints the array of filters
for the single SFF CAN identifiers is prepared to be used by a second caller.
Therefore it is also renamed to properly describe its future functionality.
