tftp: check incrementation for DATA and ACK packets
The 2 bytes following the opcode for DATA and ACK packets are the
block number and this should be incrementing every packet.
We should check to see that this is occurring otherwise false matches
can occur, eg L2TPv3 over UDP matches the DATA opcode but the next two
bytes are always zero.
Remove the DATA max block size assumption since this can be false if
the blksize option is used to increase it.
Fixes #2070
