Subject: [PATCH] scsi: gdth: 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.

This is a resend to tglx, with Reviews/Acks. Martin Petersen suggested
that scsi timer conversions should go via the timer tree.
