Commit 1e5b3b3fe9e0 ("rtl8xxxu: Adjust RX skb size to include space for
phystats") increased the skb size when aggregation is enabled but decreased
it for the aggregation disabled case.
As a result, if a frame near the maximum size is received,
rtl8xxxu_rx_complete() is called with status -EOVERFLOW and then the
driver starts to malfunction and no further communication is possible.
Restore the skb size in the aggregation disabled case.
