[PATCH 20/20] exit/r8188eu: Replace the macro thread_exit with a simple return 0

Eric W. Biederman

The macro thread_exit is called is at the end of functions started
with kthread_run. The code in kthread_run has arranged things so a
kernel thread can just return and do_exit will be called.

So just have rtw_cmd_thread and mp_xmit_packet_thread return instead
of calling complete_and_exit.
