Fix TKIP, repeated fragmentation problem, and payload_size reporting
1. TKIP encryption
Originally, TKIP encryption issues msdu + mpdu encryption on every
fragment. Change the behavior to msdu encryption on the whole
packet, then mpdu encryption on every fragment.
2. Avoid repeated fragmentation when !host_encrypt.
We only need do fragmentation when using host encryption. Otherwise
we only need pass the whole packet to driver, letting driver do the
fragmentation.
3. change the txb->payload_size to correct value
FW will use this value to determine whether to do fragmentation. If
we pass the wrong value, fw may cut on the wrong bound which will
make decryption fail when we do host encryption.
NOTE: This requires changing drivers (hostap) that have
extra_prefix_len used within them (structure member name change).
