Static analysis reports this problem
sev-dev.c:1094:19: warning: The left operand of '==' is a garbage value
if (rc && (error == SEV_RET_SECURE_DATA_INVALID)) {
~~~~~ ^
The error variable may not be set by the call to
sev_platform_init(). So initialize error to SEV_RET_SUCCESS.
Fixes: 1d55fdc85799 ("crypto: ccp - Retry SEV INIT command in case of integrity check failure.")
