net/hns3: fix index to look up table in NEON Rx

[ upstream commit 6bec7c50be7a38c114680481f285976142df40d0 ]

In hns3_recv_burst_vec(), the index to get packet length and data
size are reversed. Fortunately, this doesn't affect functionality
because the NEON Rx only supports single BD in which the packet
length is equal to the date size. Now this patch fixes it to get
back to the truth.
