[PATCH] nfp: bpf: make array exp_mask static, makes object smaller

[Colin King]

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

Don't populate the array exp_mask on the stack but instead make it
static. Makes the object code smaller by 224 bytes.

Before:
   text    data     bss     dec     hex filename
  77832    2290       0   80122   138fa ethernet/netronome/nfp/bpf/jit.o

After:
   text    data     bss     dec     hex filename
  77544    2354       0   79898   1381a ethernet/netronome/nfp/bpf/jit.o

(gcc version 9.2.1, amd64)
