[PPP]: Fixed hardware RX checksum handling
When we pull the PPP protocol off the skb, we forgot to update the
hardware RX checksum. This may lead to messages such as
dsl0: hw csum failure.
Similarly, we need to clear the hardware checksum flag when we use
the existing packet to store the decompressed result.
