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.

treewide: init_timer() -> setup_timer()
This mechanically converts all remaining cases of ancient open-coded timer
setup with the old setup_timer() API, which is the first step in timer
conversions. This has no behavioral changes, since it ultimately just
changes the order of assignment to fields of struct timer_list when
finding variations of:
init_timer(&t);
f.function = timer_callback;
t.data = timer_callback_arg;
to be converted into:
setup_timer(&t, timer_callback, timer_callback_arg);
The conversion is done with the following Coccinelle script, which
is an improved version of scripts/cocci/api/setup_timer.cocci, in the
following ways:
- assignments-before-init_timer() cases
- limit the .data case removal to the specific struct timer_list instance
- handling calls by dereference (timer->field vs timer.field)
