Alexander Potapenko da3418ad74 lib/stackdepot.c: fix global out-of-bounds in stack_slabs 
[ Upstream commit 305e519ce48e935702c32241f07d393c3c8fed3e ]

Walter Wu has reported a potential case in which init_stack_slab() is
called after stack_slabs[STACK_ALLOC_MAX_SLABS - 1] has already been
initialized.  In that case init_stack_slab() will overwrite
stack_slabs[STACK_ALLOC_MAX_SLABS], which may result in a memory
corruption.
