x86/sev: Don't hang but terminate on failure to remap SVSM CA
Commit
09d35045cd0f ("x86/sev: Avoid WARN()s and panic()s in early boot code")
replaced a panic() that could potentially hit before the kernel is even
mapped with a deadloop, to ensure that execution does not proceed when the
condition in question hits.
As Tom suggests, it is better to terminate and return to the hypervisor
in this case, using a newly invented failure code to describe the
failure condition.
