crypto: ccp - Ensure psp_ret is always init'd in __sev_platform_init_locked() 



Initialize psp_ret inside of __sev_platform_init_locked() because there
are many failure paths with PSP initialization that do not set
__sev_do_cmd_locked().

Fixes: e423b9d7: ("crypto: ccp - Move SEV_INIT retry for corrupted data")
