scsi: bnx2i: 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.

There was a seemingly missing call to initialize the timer in one handler,
so this was added to remove the open-coded initialization.
