Johannes Berg 554891e63a mac80211: move packet flags into packet 
commit 8c0c709eea

    mac80211: move cmntr flag out of rx flags

moved the CMNTR flag into the skb RX flags for
some aggregation cleanups, but this was wrong
since the optimisation this flag tried to make
requires that it is kept across the processing
of multiple interfaces -- which isn't true for
flags in the skb. The patch not only broke the
optimisation, it also introduced a bug: under
some (common!) circumstances the flag will be
set on an already freed skb!

However, investigating this in more detail, I
found that most of the flags that we set should
be per packet, _except_ for this one, due to
a-MPDU processing. Additionally, the flags used
for processing (currently just this one) need
to be reset before processing a new packet.

Since we haven't actually seen bugs reported as
a result of the wrong flags handling (which is
not too surprising -- the only real bug case I
can come up with is an a-MSDU contained in an
a-MPDU), I'll make a different fix for rc.
