parentIB/hfi1: Convert timers to use timer_setup() (diff)
RDMA/cxgb3: Convert timers to use timer_setup()
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. Also removes an unused timer.
