When the guest kernel patches are fixed to remove the uninitialized memory from the response, we can remove our check for EIO to avoid doing anything to the firmware error value. Added in PR#3

Add a workaround to Linux 6.1's sev-guest lockout
56d47e8 
The IV reuse fix 47894e0fa6a5 works against the host's throttling by
making the sev-guest device useless when throttled. The x86/urgent fix
72f7754dcf31 that merged to tip on March 16 still hasn't made it to
some distros, so this workaround is still needed temporarily.

Issue google#40 is to revert this change at the appropriate time. The same
fix for google#40 includes the fix for google#5.
