crypto: ccp - Declare PSP dead if PSP_CMD_TEE_RING_INIT fails
tee_init_ring() only declares PSP dead if the command times out.
If there is any other failure it is still considered fatal though.
Set psp_dead for other failures as well.
Fixes: 949a0c8dd3c2 ("crypto: ccp - Move direct access to some PSP registers out of TEE")
