net: hns3: adjust rss indirection table configure command

For the max rss size of PF may be up to 512, so adjust the
command of configuring rss indirection table to support
queue id larger than 255. The width of queue id is extended
from 8 bits to 10 bits. The high 2 bits are stored in filed
rss_qid_h when the queue id is larger than 255.
