How does the user distinguish between KVM_EXIT_FAIL_ENTRY due to an exit

need separate exit codes (with documentation in api.txt).
In both cases the vm fails entry, and I don't think the hardware entry
failure reason codes would overlap between the vmx->fail case and exit
reasons with bit 31 set, so why should there be such distinction
between both cases?

Only 5 more error codes (28->33) and we have overlap.

If you return the new codes with bit 31 still set then we can use the existing KVM_EXIT_FAIL_ENTRY.
