kernel/work_q: Spinlockify

Browse source 
Each work_q object gets a separate spinlock to synchronize access
instead of the global lock.  Note that there was a recursive lock
condition in k_delayed_work_cancel(), so that's been split out into an
internal unlocked version and the API entry point that wraps it with a
lock.
