[PATCH] crypto: initialize error

[Tom Rix]

clang static analysis reports this problem
drivers/crypto/ccp/sev-dev.c:1347:3: warning: 3rd function call
  argument is an uninitialized value [core.CallAndMessage]
    dev_err(sev->dev, "SEV: failed to INIT error %#x, rc %d\n",
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

__sev_platform_init_locked() can return without setting the
error parameter, causing the dev_err() to report a gargage
value.

Fixes: 3d725965f836 ("crypto: ccp - Add SEV_INIT_EX support")
