We can't return with VM_FAULT_SIGBUS | VM_FAULT_LOCKED; the core code will not unlock the folio in this instance. Introduce a new "unlock" error exit to handle this case. Use it to handle the "folio is truncated" check, and change the "writeback interrupted by a fatal signal" to do a NOPAGE exit instead of letting the core code install the folio currently under writeback before killing the process.
