[PATCH] net: hns3: make array spec_opcode static const, makes object smaller

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Don't populate the array spec_opcode on the stack but instead make it
static const. Makes the object code smaller by 48 bytes.

Before:
   text    data     bss     dec     hex filename
   6914    1040     128    8082    1f92 hns3/hns3vf/hclgevf_cmd.o

After:
   text    data     bss     dec     hex filename
   6866    1040     128    8034    1f62 hns3/hns3vf/hclgevf_cmd.o

(gcc version 9.2.1, amd64)
