WNM: Fix deinit path to clean neighbor report count 

wnm_deallocate_memory() left wnm_num_neighbor_report set while freeing
the allocated buffer of neighbor reports. If this function was called
twice in a row without having went through new neighbor report parsing,
invalid pointers could have been freed resulted in segfault.
