s390/sclp: Convert timers to use timer_setup()

Browse Source 
In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. Instead of creating an external static
data variable, just define a separate callback which encodes the "force
restart" desire.
