wireless: move sequence number arithmetic to ieee80211.h
Move the sequence number arithmetic code from mac80211 to ieee80211.h so others can use it. Also rename the functions from _seq to _sn, they operate on the sequence number, not the sequence_control field. Also move macros to convert the sequence control to/from the sequence number value from various drivers. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
