slab: remove __alloc_size attribute from __kmalloc_track_caller
Commitc37495d625
("slab: add __alloc_size attributes for better bounds checking") added __alloc_size attributes to a bunch of kmalloc function prototypes. Unfortunately the change to __kmalloc_track_caller seems to cause clang to generate broken code and the first time this is called when booting, the box will crash. While the compiler problems are being reworked and attempted to be solved [1], let's just drop the attribute to solve the issue now. Once it is resolved it can be added back.
