Pullup rev 1.90 (requested by chs in ticket #914)
 Remove the assertion in uvm_swapout_threads() about LSONPROC lwps
 not running on the same CPU as the swapper. l_stat is protected by
 sched_lock, which isn't held here, so we can race with that lwp
 starting to run and see its l_cpu not updated yet, as in PR 31870.
 we check l_stat again in uvm_swapout() while holding sched_lock,
 so the race itself is harmless.
