The functions _base_readl_aero() and _base_readl() used for an adapter
base_readl() method are implemented using a regular readl() call which
performs internally a conversion to CPU endianness (le32_to_cpu()) of
the values read. The users of the ioc base_readl() method should thus
not convert again the values read using le16_to_cpu().
Fixing this removes sparse warnings.
