wlan: Return NULL if zero is passed as argument to allocate memory
While allocating memory if zero is passed as argument then kernel will
return address ZERO_SIZE_PTR(0x10) leading to pass NULL check, which is
usually done after every memory allocation. Hence when zero is passed to
allocate memory then return NULL without calling kmalloc.
While initializing neighbor roam data structure, don't allocate memory
if neighbor roam channel list is empty.
