libpayload: cbfs: Fix ram_media map() error return value
The correct return value for errors on a cbfs_media->map() call is CBFS_MEDIA_INVALID_MAP_ADDRESS, not NULL. Not sure if that's the best choice (since 0xffffffff is probably a more likely valid address than 0 there), but that's what the upper layers expect right now. BRANCH=veyron BUG=None TEST=Press CTRL+L with an RW_LEGACY section filled with 0xff. Observe how cbfs_get_header() returns failure without doing a bunch of NULL pointer accesses first (not that those have any visible effect on Veyron, but that's another problem...)
