The class function and implementations for updating launch data return
a code in case of error. In some cases an error message is generated and
in other cases, just the error return value is used.

This small refactor adds an 'Error **errp' parameter to all functions
which consistently set an error condition if a non-zero value is
returned.

Why were we returning 1 before? Was that a mistake?
Maybe we should mention it in the patch or fix it in another patch.

Pre-existing, but while we're at it maybe we can remove ret.

Ditto for the 2 changes, although IIUC we never check the return value 
of snp_launch_update_cpuid().

The error returns were changed to -1 for consistency, but on reflection, without
changing every return in this file it had the reverse effect. I'll revert these
back to the original return values.

I did however spot a pre-existing bug when reverting this though.
sev_encrypt_firmware() only considers a negative result from launch_update() as
an error, but the function returns 1 on some errors. I've added a new patch in
v4 that fixes this error.
