[tlul/rtl] Modify readback check error reporting logic

Currently, only a readback error check is reported when the `error_i` signal is not raised. However, as this signal is also raised when there is no activity on the TL-UL bus, we might miss some readback failures. This commit modifies the error reporting logic to also report the readback mismatch when the error signal is raised. Closes #24698. Signed-off-by: Pascal Nasahl <[email protected]>
