Currently when the PSP returns a SECURE_DATA_INVALID error on INIT or
INIT_EX the driver retries the command once which should reset the PSP's
state SEV related state, meaning the PSP will regenerate its keying
material. This is logged with a dbg log but given this will change
system state this should be logged at a higher priority and with more
information.
