kaweth: Fix memory leak in kaweth_control()
commit 051b982bcc620695de629d29c333c95b66e9b95e upstream.
kaweth_control() never frees the buffer that it allocates for the USB
control message. Test case:
while :; do ifconfig eth2 down ; ifconfig eth2 up ; done
This is a tiny buffer so it is a slow leak. If you want to speed up the
process, you can change the allocation size to e.g. 16384 bytes, and it
will consume several megabytes within a few minutes.
