    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...)
