Commit 1a2473f0cbc0 ("kasan: improve vmalloc tests") added the
vmalloc_percpu KASAN test with the assumption that __alloc_percpu always
uses vmalloc internally, which is tagged by KASAN.
However, __alloc_percpu might allocate memory from the first per-CPU
chunk, which is not allocated via vmalloc(). As a result, the test might
fail.
Remove the test until proper KASAN annotation for the per-CPU allocated
are added; tracked in https://bugzilla.kernel.org/show_bug.cgi?id=215019.
