PR kern/38707 scheduler related deadlock during build.sh
Fail sched_catchlwp() if mutex_tryenter() on the remote CPU's state fails.
Seems to work around the issue described in this PR.
XXX Stealing jobs from remote CPUs could probably be moved into the idle
loop, making the locking quite a bit simpler.
