drivers: net: ppp: fix removing CRC16 from packet
CRC16 was removed by simply decreasing length of the last fragment by 2.
This worked as long as last fragment was longer than 1 byte. If not,
then last fragment was corrupted (its length ended up being 65535),
leading to undefined behavior.
Fix CRC16 removal by utilizing recently introduced
net_pkt_remove_tail(), that properly handles multiple fragments.
