From: Jijie Shao <shaojijie@huawei.com>

[ Upstream commit 878406d4d6ef85c37fab52074771cc916e532c16 ]

Currently, HCLGE_FD_AD_QID has only 10 bits and supports a
maximum of 1023 queues. However, there are actually scenarios
where the queue_id exceeds 1023.

This patch adds an additional bit to HCLGE_FD_AD_QID to ensure
that queue_id greater than 1023 are supported.
