target: Convert DIF emulation to use cmd->prot_type

This patch changes existing DIF emulation to check the command descriptor's
prot_type, instead of what the backend device is exposing in pi_prot_type.

Since this value is already set in sbc_check_prot(), go ahead and use it to
allow protected fabrics to function with unprotected devices.
