ioat/perf: allow queue depths > 256 



Currently the task and buffer pools are hardcoded to
512 each.  This effectively limits the queue depth
per channel to 256 since we need both source and
destination buffers from the buffer pool.  So make
the pool sizes dynamic based on the user's queue depth
input.
