splat taskq:front: Reduce stack frame
The slightly increased size of the taskq_ent_t when debugging is
enabled has pushed the taskq:front splat test over frame size
limit. To resolve this dynamically allocate the taskq_ent_t
structures so they are part of the heap instead of the stack.
In function 'splat_taskq_test6_impl'
error: the frame size of 1648 bytes is larger than 1024 bytes
