Changed crypto method from requiring a struct ieee80211_device reference
to the init handler. Instead we now have a get/set flags method for
each crypto component.
Setting of TKIP countermeasures can now be done via
set_flags(IEEE80211_CRYPTO_TKIP_COUNTERMEASURES)

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).

Fixed a kernel oops on module unload by adding spin lock protection to
ieee80211's crypt handlers (thanks to Zhu Yi)
Modified scan result logic to report WPA and RSN IEs if set (vs.being
based on wpa_enabled)
Added ieee80211_device as the first parameter to the crypt init()
method. TKIP modified to use that structure for determining whether to
countermeasures are active.

NOTE: Looks like scripts/Lindent generated output different
than the Lindented version already in-kernel, hence all the
whitespace deltas... *sigh*

No code changes, just Lindent + manual fixups.
This prepares us for updating to the latest Intel driver code, plus
gives the source code a nice facelift.
