rsi: fix memory leak in rsi_load_ta_instructions()
Memory allocated by kmemdup() in rsi_load_ta_instructions() is leaked.
But duplication of firmware data here is useless,
so the patch removes kmemdup() at all.
Found by Linux Driver Verification project (linuxtesting.org).

We use this driver for the Redpine Wifi chip on our "florida" board, and after
this commit it stopped working. Symptom was that the "wlan0" device was not
created at all. Reverting the commit makes it work again.
Apparently, the kmemdup action is needed for something. I suspect the DMA
controller is still copying the firmware data before the method returned.
Having no experience with this part of the kernel, I wasn't able to come up
with a more constructive solution than just reverting the patch.
