Possible null dereference of variable "*pkt" in function call

Either I'm misunderstanding, or this is bogus.

when *pkt is allocated by the various child functions (e.g. ieee80211softmac_disassoc_deauth), it is always checked for NULL.

Finally, line 453 does another NULL check.

What is the report trying to say?
