If a Flymake backend calls a "stale" report function,
flymake--handle-report might be called for a backend function that is
no longer in the flymake--backend-state hash table.  This patch makes
that erroneous situation slightly more explicit.

* lisp/progmodes/flymake.el (flymake--handle-report): Improve
error reporting.
