RDMA/mlx4: Don't continue event handler after memory allocation failure
The failure to allocate memory during MLX4_DEV_EVENT_PORT_MGMT_CHANGE
event handler will cause skip the assignment logic, but
ib_dispatch_event() will be called anyway.
Fix it by calling to return instead of break after memory allocation
failure.
Fixes: 00f5ce99dc6e ("mlx4: Use port management change event instead of smp_snoop")
