IB/mlx4: fix unitialised variable is_mcast
Commit 297e0dad7206 ("IB/mlx4: Handle Ethernet L2 parameters for IP based GID addressing") introduced a bug where is_mcast is now no longer initialized on the non-multicast condition and so it can be any random value from the stack. This issue was detected by cppcheck: [drivers/infiniband/hw/mlx4/ah.c:103]: (error) Uninitialized variable: is_mcast Simple fix is to initialise is_mcast to zero.
