net: pktgen: don't abuse current->state in pktgen_thread_worker()
Commit 1fbe4b46caca "net: pktgen: kill the Wait for kthread_stop
code in pktgen_thread_worker()" removed (in particular) the final
__set_current_state(TASK_RUNNING) and I didn't notice the previous
set_current_state(TASK_INTERRUPTIBLE). This triggers the warning
in __might_sleep() after return.
Afaics, we can simply remove both set_current_state()'s, and we
could do this a long ago right after ef87979c273a2 "pktgen: better
scheduler friendliness" which changed pktgen_thread_worker() to
use wait_event_interruptible_timeout().
