kernel - Fix several taskqueue livelocks
* Taskqueue was trying to issue callout_*() operations with a spin-lock
held on callouts associated with other cpus. This can livelock the
system.
* Unlock the taskqueue spinlock when messing with callout_*() operations.
* Fixes an indefinite spin lock panic from drm/ttm.
