From: "Mike Rapoport (IBM)" <rppt@kernel.org>

Since commit f6f37d9320a1 ("arm64: select KASAN_VMALLOC for SW/HW_TAGS
modes") KASAN_VMALLOC is always enabled when KASAN is on. This means
that allocations in module_alloc() will be tracked by KASAN protection
for vmalloc() and that kasan_alloc_module_shadow() will be always an
empty inline and there is no point in calling it.

Drop meaningless call to kasan_alloc_module_shadow() from
