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

Don't populate the array states on the stack but instead it
static const. Makes the object code smaller by 79 bytes.

Before:
text data bss dec hex filename
21309 8304 192 29805 746d drivers/net/ethernet/mellanox/mlx4/qp.o

After:
text data bss dec hex filename
21166 8368 192 29726 741e drivers/net/ethernet/mellanox/mlx4/qp.o

(gcc version 10.2.0)
