kernel/queue: Spinlockify
Straightforward port. Each struct k_queue object gets a spinlock to
control obvious data ownership.
Note that this port actually discovered a preexisting bug: the -ENOMEM
case in queue_insert() was failing to release the lock. But because
the tests that hit that path didn't rely on other threads being
scheduled, they ran to successful completion even with interrupts
disabled. The spinlock API detects that as a recursive lock when
asserts are enabled.
