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.
