Andrey Konovalov 1c61990d37 kasan: fix bad call to unpoison_slab_object 
Commit 29d7355a9d ("kasan: save alloc stack traces for mempool") messed
up one of the calls to unpoison_slab_object: the last two arguments are
supposed to be GFP flags and whether to init the object memory.

Fix the call.

Without this fix, __kasan_mempool_unpoison_object provides the object's
size as GFP flags to unpoison_slab_object, which can cause LOCKDEP reports
(and probably other issues).
