kmem-cache: Use a taskq for async allocations
Shift the asynchronous allocations over to use the taskq interfaces.
This allows us to abandon the kernels delayed work queue interface
and all the compatibility code it requires.
This code never actually used the delay functionality it was just
done this way to leverage the existing compatibility code. All that
is required is a thread context to perform the allocation in. The
only thing clever in this change is that we take advantage of the
preallocated task queue entries to avoid a memory allocation.
