Modified Files:
        src/sys/kern: kern_exit.c kern_lwp.c sys_lwp.c
        src/sys/sys: lwp.h

Log Message:
exit_lwps, lwp_wait: fix a race condition by re-trying if p_lock was dropped
in a case of process exit.  Necessary to re-flag all LWPs for exit, as their
state might have changed or new LWPs spawned.

Should fix PR/46168 and PR/46402.
