psp: validate IPv4 header fields in psp_dev_rcv()

Browse source

psp_dev_rcv() is called from the NIC driver's RX completion path
before the frame reaches ip_rcv_core(), so the IP header has not
been validated in SW, yet. We expect that the device has done
all this validation, but let's also add the SW checks, to avoid
surprises.
