By design the crm has no idea which node or plugin is used (or were
tried and failed).
So it would be impossible to for it recover the RA on its own.

It _may_ make sense for the stonithd to unload any plugin that reports
a failed stonith action (and thus causing the monitor to eventually
fail) but I'll leave that for Dejan to think about :-)
