mac80211: headers: fix lockdep_assert_not_held()

LOCK_STATE_HELD define was omitted during backport of
lockdep_assert_not_held() which leads to build failures of kernels with
CONFIG_LOCKDEP=y:

 backports-5.15.8-1/backport-include/linux/lockdep.h:16:47: error: 'LOCK_STATE_HELD' undeclared (first use in this function)

Fix it by adding missing LOCK_STATE_HELD define.
