KVM: SVM: Convert plain error code numbers to defines

Browse source

Convert VMGEXIT SW_EXITINFO1 codes from plain numbers to proper defines.

Opportunistically update the comment for the malformed input "sub-error"
codes to state that they are defined by the GHCB, and to capure the
relationship to the malformed input response.

No functional change intended.
