[PATCH] Unifi AC: remove bs-partition ro-flag

[Fabian Bläse]

Sollten wir wohl aufnehmen, bis wir auf eine OpenWRT Version updaten, die das schon drin hat.
Ist sonst etwas umständlich, die Partition zu reparieren, weil man das ohne TFTP nichta mehr geflasht bekommt.

Sieht soweit gut aus, habs aber selbst nicht ausprobiert.
