76860c72e1 malloc_usable_size: clean abort on invalid region 
It's the region pointer that can be NULL here, and p was checked at the
beginning of the function. Also fix the test accordingly.

5275563252 fix C++ sized deallocation check false positive 
This is a compatibility issue triggered when both slab canaries and the
C++ allocator overloads providing sized deallocation checks are enabled.

The boundary where slab allocations are turned into large allocations
due to not having room for the canary in the largest slab allocation
size class triggers a false positive in the sized deallocation check.

b90f650153 fix sized deallocation check with large sizes 
The CONFIG_CXX_ALLOCATOR feature enables sanity checks for sized
deallocation and this wasn't updated to handle the introduction of
performing size class rounding for large sizes.
