rtlwifi: rtl8192cu: Fix endianian issues
Driver rtlwifi fails on a big-endian host.
These changes have been tested on a Mac PowerBook G4, which has
a PPC processor.
Although this patch touches some of the code that will affect endian
issues on PCI hardware through drivers rtl8192ce, rtl8192se, and
rtl8192de, these have not been tested due to lack of suitable hardware.

mac80211: transmit fragment list to drivers
Drivers can usually handle fragmented packets
much easier when they get the entire list of
fragments at once. The only thing they need to
do is keep enough space on the queues for up
to ten fragments of a single MSDU.
This allows them to implement this with a new
operation tx_frags.

mac80211: Get rid of search loop for rate group index
Finding the group index for a specific rate is done by looping through
all groups and returning if the correct one is found. This code is
called for each tx'ed frame and thus it makes sense to reduce its
runtime.
Do this by calculating the group index by this formula based on the SGI
and HT40 flags as well as the stream number:
Hence, the groups are ordered by th HT40 flag first, then by the SGI
flag and afterwards by the number of used streams.
This should reduce the runtime of minstrel_ht_get_group_idx
considerable.

mac80211: remove crypto special case for auth frames
The shared key authentication frame that needs to be
encrypted (the third one in the shared key handshake)
is directly encrypted in ieee80211_send_auth and the
IEEE80211_TX_INTFL_DONT_ENCRYPT is set. All others
are not encrypted, so the only way to get to this is
erroneously on no-monitor AP side.
Remove the special case for authentication frames to
fix the AP shared key side when operating without
cooked monitor interfaces -- with cooked monitor the
IEEE80211_TX_INTFL_DONT_ENCRYPT also gets set, so we
never get here -- an AP never encrypts auth frames.

authentication frames, instead of none.
