mac80211: Mark a destination sequence number as valid when a PREQ is received.
If a PREQ frame is received giving us a fresher DSN than what we have, record the new dsn and mark it as valid. This patch fixes a bug in the setting of the MESH_PATH_DSN_VALID flag. Also, minor fix to coding style on that file. Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
