wiphy: make wiphy_band_is_disabled return more descriptive

Browse Source 
The function wiphy_band_is_disabled() return was a bit misleading
because if the band was not supported it would return true which
could be misunderstood as the band is supported, but disabled.
There was only one call site and because of this behavior
wiphy_band_is_disabled needed to be paired with checking if the
band was supported.

To be more descriptive to the caller, wiphy_band_is_disabled() now
returns an int and if the band isn't supported -ENOTSUP will be
returned, otherwise 1 is returned if the band is disabled and 0
otherwise.
