Sam Protsenko de4e4edaff usb: gadget: g_dnl: Sync internal SN variable with env
Since commit 842778a09104 ("usb: gadget: g_dnl: only set iSerialNumber
if we have a serial#") "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, let's update internal serial number variable (g_dnl_serial)
when "serial#" env var is changed.
