libipw: split ieee->networks into small pieces
The ieee->networks consists of 128 struct libipw_network entries. If we allocate this chunk of memory altogether, it ends up with an order 4 page allocation. High order page allocation is likely to fail on system high load. This patch splits the big chunk memory allocation into small pieces, each is 344 bytes, allocates them with 128 times.
