treewide: setup_timer() -> timer_setup() (2 field)

This converts all remaining setup_timer() calls that use a nested field
to reach a struct timer_list. Coccinelle does not have an easy way to
match multiple fields, so a new script is needed to change the matches of
"&_E->_timer" into "&_E->_field1._timer" in all the rules.
