One hash_node is still left in hash bucket list while the memory
has been freed by normal operation, suspect that maybe two same
hash_node is existed in hash bucket list before, add debugging code
to detect this problem earlier.

While the Linux kernel provides a generic hash table data structure, it
makes the assumption that it will always be referred to statically, so
as to avoid having to store the size of the hash table's internal array.
This limitation means reusing this data type generically is difficult or
impossible.
Add a very simple hash table implementation to WLAN for general use,
which stores its own size information, and assumes all input keys will
be pointers. Build on top of the recently added single-linked list
implementation added in I2959f34649a0d8e0b312d9d67c81de17753b9b6c to
reduce memory overhead.
