Massage the error message for the sanity check on SPTEs when freeing a shadow page to be more verbose, and to print out all shadow-present SPTEs, not just the first SPTE encountered. Printing all SPTEs can be quite valuable for debug, e.g. highlights whether the leak is a one-off or widepsread, or possibly the result of memory corruption (something else in the kernel stomping on KVM's SPTEs). Opportunistically move the MMU_WARN_ON() into the helper itself, which will allow a future cleanup to use BUILD_BUG_ON_INVALID() as the stub for MMU_WARN_ON(). BUILD_BUG_ON_INVALID() works as intended and results in the compiler complaining about is_empty_shadow_page() not being declared.
