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)
