I'd rather say it tries to free never allocated memory? Look at mts_numallocs.

(kgdb) p ((struct malloc_type_internal *)M_80211_NODE->ks_handle)->mti_stats[0]
$20 = {mts_memalloced = 0, mts_memfreed = 61440, mts_numallocs = 0,
mts_numfrees = 5, mts_size = 0, _mts_reserved1 = 0, _mts_reserved2 =
0,
_mts_reserved3 = 0}
(kgdb) p ((struct malloc_type_internal *)M_80211_NODE->ks_handle)->mti_stats[1]
$21 = {mts_memalloced = 0, mts_memfreed = 73728, mts_numallocs = 0,
mts_numfrees = 6, mts_size = 0, _mts_reserved1 = 0, _mts_reserved2 =
0,
_mts_reserved3 = 0}
