gro: Reset dev pointer on reuse
On older kernels the VLAN code may zero skb->dev before dropping
it and causing it to be reused by GRO.
Unfortunately we didn't reset skb->dev in that case which causes
the next GRO user to get a bogus skb->dev pointer.
This particular problem no longer happens with the current upstream
kernel due to changes in VLAN processing.
However, for correctness we should still reset the skb->dev pointer
in the GRO reuse function in case a future user does the same thing.
