Subject: net/mlx4: make the array states static const, makes object smaller
Patch-mainline: v5.15-rc1
Git-commit: 7cdd0a89ec70ce6a720171f1f7817ee9502b134c
References: jsc#SLE-19256

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)
