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

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

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
