    kasan: Use kasan_md_unsupported() to check for invalid addresses
    
    The subsequent assert verifies that the address is in the kernel map
    anyway, and this removes uses of the MD DMAP_*_ADDRESS constants from MI
    code.
    
    This fixes the amd64 KASAN build after commit 4dd828c80828 ("amd64: add
    kva_layout").
