wifi-scripts: update phys after rename_phy_by_name call

This fixes a failed bring up of the radio on bootup
if the model defines a rename of phy in its /etc/board.json.
This specifically impacts Redmi AX6S and any router that does so
in its /etc/board.json. The fix fortunately is simple, just update
phy name in phys after rename.

The entry that specifically causes this issue is the following:

{
	<omitted>
	"wlan": {
		"wl0": {
			"path": "platform/18000000.wmac",
			"info": {
				"antenna_rx": 15,
				"antenna_tx": 15,
				"bands": {
					"2G": {
						"ht": true,
						"max_width": 40,
						"modes": [
							"NOHT",
							"HT20",
							"HT40"
						],
						"default_channel": 1
					}
				},
				"radios": [
				]
			}
		},
	...
}

The issue is that after rename, referenced phy in config is going to be
wl0 but in phys array it is still phy0; and so it fails to find phy
and does not bring up radio.
