Subject: [PATCH mm 05/11] kasan: update kasan_poison documentation comment

From: Andrey Konovalov <andreyknvl@...gle.com>

The comment for kasan_poison says that the size argument gets aligned by
the function to KASAN_GRANULE_SIZE, which is wrong: the argument must be
already aligned when it is passed to the function.

Remove the invalid part of the comment.
