r8169: tweak max read request size for newer chips also in jumbo mtu mode

Browse Source 
[ Upstream commit 5e00e16cb98935bcf06f51931876d898c226f65c ]

So far we don't increase the max read request size if we switch to
jumbo mode before bringing up the interface for the first time.
Let's change this.
