s390/ipl: fix physical-virtual confusion for diag308
Diag 308 subcodes expect a physical address as their parameter.
This currently is not a bug, but in the future physical and virtual
addresses might differ.
Fix the confusion by doing a virtual-to-physical conversion in the
exported diag308() and leave the assembly wrapper __diag308() alone.
Note that several callers pass NULL as addr, so check for the case when
NULL is passed and pass 0 to hardware since virt_to_phys(0) might be
nonzero.
