3.16.79-rc1 review patch. If anyone has any objections, please let me know.

commit 6f3ef5c25cc762687a7341c18cbea5af54461407 upstream.
In the implementation of i2400m_op_rfkill_sw_toggle() the allocated buffer for cmd should be released before returning. The documentation for i2400m_msg_to_dev() says when it returns the buffer can be reused. Meaning cmd should be released in either case. Move kfree(cmd) before return to be reached by all execution paths.
