[net-next 7/9] i40e: make const array patterns static, reduces object code size

[Jeff Kirsher]

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

Don't populate const array patterns on the stack, instead make it
static. Makes the object code smaller by over 60 bytes:

Before:
   text    data     bss     dec     hex filename
   1953     496       0    2449     991 i40e_diag.o

After:
   text    data     bss     dec     hex filename
   1798     584       0    2382     94e i40e_diag.o

(gcc 6.3.0, x86-64)
