This patch prevent u-boot from hanging on a UltraZed EG board (zynqmp).

Without the patch, (drv = env_driver_lookup(ENVOP_INIT, prio)) evaluates to 0, causing prio = 0 Then, (!prio) is hit, returning -ENODEV causing a stall.

With the patch, instead of returning -ENODEV and causing a stall, we set gd->env_addr (is this really needed?) and then mark gd->env_valid = ENV_INVALID to use the default env.

Applied to u-boot/master, thanks!
