Since only the SIMs that support WLUN reporting call this, that limits the damage.
It may be the case we have to probe LUNs first and not probe WLUNs at all if that fails (some older, reduced command CDB sets don't have REPORT LUNS at all). For the moment, it's fine.

3060	There are several formats for the LUN address method (Peripheral, Flat, Extended flat, Long). And we don't support them.
