Since 842778a09104 commit, "fastboot devices" stopped to show correct device serial number for TI boards, showing this line instead:
???????????? fastboot
This is because serial# env variable could be set after g_dnl gadget was initialized (e.g. by using env_set() in the board file).
To fix this, before checking g_dnl_serial, let's re-check if we have valid serial# value. And if so, let's set it as g_dnl_serial value.
