Paolo Bonzini cd1bd53a66 qemu-timer: introduce timer_deinit
In some cases, a timer was set to NULL so that we could check if it is
initialized.  Use the timer_list field instead, and add a timer_deinit
function that NULLs it.

It then makes sense that timer_del be a no-op (instead of a crasher) on
such a de-initialized timer.  It avoids the need to poke at the timerlist
field to check if the timers are initialized.
