rpmb_dev: Fix RPMB_REQ_DATA_READ command

Add ".check_key_programmed = true." for RPMB_REQ_DATA_READ such that
we can check whether the rpmb key has been programmed before executing
RPMB_REQ_DATA_READ command.

"JEDEC STANDARD Universal Flash Storage (UFS) Version 3.0" specifies
that data access before the key has been programmed should return
“Authentication Key not yet programmed” (0007h)..
