  KVM: nVMX: Reset MMU back to the root MMU if loading L2 state fails for !VM-Entry (2026-10-14 16:42:40 +0200)

----------------------------------------------------------------
Even more x86 fixes:

- Avoid a false positive panic in the #PF handler, if the kernel triggers
  a page fault within the asynchronous page fault handler before the flags
  are reset.  This can happen for example because of a perf NMI.

- Always reset a vCPU's MMU pointer back to the root MMU when loading
  nested guest state fails during RSM or KVM_SET_NESTED_STATE.  Otherwise,
  KVM tries to run a non-nested guest with a nested MMU, which can result
  in a NULL pointer dereference attempting to get the nested MMU's pgd
  (EPTP or nested CR3).
