[PATCH] FILS: Fix memory leak if AES-SIV encryption fails

[Benjamin Berg]

From: Benjamin Berg <benjamin.berg at intel.com>

The dynamically allocated header was not free'ed in the error path. Add
the appropriate os_free call.

Fixes: b729fd8df9f6 ("FILS: Use AEAD cipher to protect EAPOL-Key frames (AP)")
