IPoIB: Fix kernel unaligned access on ia64
Fix misaligned access faults on ia64: never cast a misaligned
neighbour->ha + 4 pointer to union ib_gid type; pass a void * pointer
instead. The memcpy was being optimized to use full word accesses
because the compiler thought that union ib_gid is always aligned.
The cast in IPOIB_GID_ARG is safe, since it is fixed to access each
byte separately.
