kernel: rtl8306: fix port link status
In case the link changes from down to up, the register is only updated on read. If the link failed/was down, this bit will be 0 until after reading this bit again. Fixes a reported link down by swconfig alebit the link is up (query for the link again will show the correct link status) Signed-off-by: Mathias Kresin <dev@kresin.me>
