[PATCH] Revert "env: Load env when ENV_IS_NOWHERE is only location selected"

This reverts commit 8d61237edbf6314a701cf78da2c5893a73ff5438.

This commit broke environment on literally every board I have access
to, with this revert in place, environment works as it should again.
The problem I observe with this patch is that saved environment in
either SPI NOR or eMMC is never used, the system always falls back
to default environment. The 'saveenv' command does succeed, but then
after reset, the default env is again used.

Furthermore, the commit introduced duplicate code in env_init(), this:
"
	if (!prio) {
		gd->env_addr = (ulong)&default_environment[0];
		gd->env_valid = ENV_INVALID;

		return 0;
	}

	if (ret == -ENOENT) {
		gd->env_addr = (ulong)&default_environment[0];
		gd->env_valid = ENV_INVALID;

		return 0;
	}
"

Furthermore, the commit is missing DCO SoB line.

Also note that upstream does not support UltraZed EG board, so
this might have been a patch pulled from downstream which did
depend on some other downstream behavior.
