Make O(1) checks for corruption and list state to rule out
suspicion of double free and memory corruption. Only traverse
the memory tracking list to differentiate between memory corruption
and freeing an untracked pointer.
Since we check for corruption before traversing the list, the qdf_mem_free
api may crash with a use after free signature before printing out the
double free error message.

Freeing a null pointer shouldn't do anything.
Some code relies on this. Specifically, in a
rare scenario, an allocation is made outside of
a spinlock and may freed without being used or
verified inside the spinlock.

The net buf tracking feature spend most of its time allocating
tracking cookies. By not tracking these tracking cookies in
qdf we achieve a 90% time saving. By keeping a freelist and
avoiding allocations altoogether, we save another 90%. This
feature is 99% cheaper. Throughput suffers less under when
the driver is forced to be cpu bound (eg. by mucking with the clockspeed).
