[PATCH 1/5] spl: romapi: Fix issue for stream mode with secure boot enabled

[Peng Fan]

When download image through ROM API for stream mode (USB, eMMC fastboot).
We uses tricky way to get the total image size:
The spl_load_simple_fit is called but the data reading is invalid,
so the image data is not really downloaded.
We should not call HAB authenticate in this tricky way. Otherwise it
will alway fail.
This patch skip the authentication only for this tricky using.
