[PATCH] slab: fix kzalloc and kstrdup caller report for CONFIG_DEBUG_SLAB

Fix kzalloc() and kstrdup() caller report for CONFIG_DEBUG_SLAB.  We must
pass the caller to __cache_alloc() instead of directly doing
__builtin_return_address(0) there; otherwise kzalloc() and kstrdup() are
reported as the allocation site instead of the real one.

Thanks to Valdis Kletnieks for reporting the problem and Steven Rostedt for
the original idea.
