wifi: mm81x: free the firmware scratch buffer on parse failures

Browse source

mm81x_fw_load_fw() allocates fw_buf before it inspects the image, but
releases it only on the success path.  The two early returns taken for a
malformed image leave one firmware-sized allocation attached to the
device, and mm81x_fw_flash() retries the load three times.

Release it on those paths too, the way mm81x_fw_load_bcf() already does.
