kasan: move _RET_IP_ to inline wrappers
Generic mm functions that call KASAN annotations that might report a bug
pass _RET_IP_ to them as an argument. This allows KASAN to include the
name of the function that called the mm function in its report's header.
Now that KASAN has inline wrappers for all of its annotations, move
_RET_IP_ to those wrappers to simplify annotation call sites.
