Xiaochen Shen 68974a46ed dmaengine: idxd: Fix max batch size for Intel IAA 
commit e8dbd6445d upstream.

>From Intel IAA spec [1], Intel IAA does not support batch processing.

Two batch related default values for IAA are incorrect in current code:
(1) The max batch size of device is set during device initialization,
    that indicates batch is supported. It should be always 0 on IAA.
(2) The max batch size of work queue is set to WQ_DEFAULT_MAX_BATCH (32)
    as the default value regardless of Intel DSA or IAA device during
    work queue setup and cleanup. It should be always 0 on IAA.

Fix the issues by setting the max batch size of device and max batch
size of work queue to 0 on IAA device, that means batch is not
supported.
