From: Colin Ian King <colin.k...@canonical.com>
Commit 297e0dad7 introduced a bug where is_mcast is now
no longer initiialised 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.
