riscv: Fix config KASAN && SPARSEMEM && !SPARSE_VMEMMAP
In order to get the pfn of a struct page* when sparsemem is enabled
without vmemmap, the mem_section structures need to be initialized which
happens in sparse_init.
But kasan_early_init calls pfn_to_page way before sparse_init is called,
which then tries to dereference a null mem_section pointer.
Fix this by removing the usage of this function in kasan_early_init.
