Replace the device completion infrastructure with the controller wide
event queue. There was a potential for the stop and ready notifications
to corrupt each other, now that cannot happen.
The stop pending flag cannot be used until devices are statically
allocated. We temporarily need to maintain a completion to handle
waiting for an object that has disappeared, but we can at least stop
scribbling on freed memory.
A future change will also get rid of the "stopping" state as it should
not be exposed to the rest of the driver.

Prepare the timer api for the arrival of dynamic creation and
destruction events from the core. It pretended to do this previously
but the core to date only used it in a static init-time only fashion.
This is an interim fix until a cleaner event queue can be developed.
1/ make all locking external to the api (add WARN_ONCE to verify)
2/ add a timer_destroy interface (to be used by the core)
3/ use del_timer_sync() prior to deallocating timer data
4/ delete the "timer_list" indirection, we only have timers allocated
for the isci_host
5/ fix detection of timer list allocation errors
