Describe the bug

The MCTP USB binding was tested using standard library malloc/free/realloc based on existing sample applications. This worked fine. If using the Zephyr sys_heap instead, a hard fault is seen when the MCTP USB binding tries to reset state after processing a packet. This occurs because k_free() does not set the memory pointer to NULL after free'ing the memory, resulting in a "double free" operation.
