s390/kasan: dynamic shadow mem allocation for modules
Move from modules area entire shadow memory preallocation to dynamic
allocation per module load.
This behaivior has been introduced for x86 with bebf56a1b: "This patch
also forces module_alloc() to return 8*PAGE_SIZE aligned address making
shadow memory handling ( kasan_module_alloc()/kasan_module_free() )
more simple. Such alignment guarantees that each shadow page backing
modules address space correspond to only one module_alloc() allocation"
