-Plugin scoreboard deadlock (plugin.lock vs start_exclusive)
-Description of problem:
-Deadlock
-
-In frame 9 the thread grabs the plugin.lock, and starts to wait for other cpus to enter exclusive idle.
-```
-#7  0x00005555555a1295 in start_exclusive () at ../hw/core/cpu-common.c:199
-#8  plugin_grow_scoreboards__locked (cpu=0x7fff0c2b4720) at ../plugins/core.c:238
-#9  qemu_plugin_vcpu_init_hook (cpu=0x7fff0c2b4720) at ../plugins/core.c:258
-```
-
-The other thread just finished a TB and do the callback to the plugin, so it will not become exclusive idle until it finishes.
-That callback tries to create a new 'scoreboard', but plugin.lock is already taken.

-Locally I'm using this fix, reverse order so we enter exclusive idle before grabbing the plugin.lock:
