What does this PR do?

The get_master_weight() of the ColumnParallelLinear first applies a transpose to the weights before calling all gather. However all gather requires the tensors to be contiguous. We can ensure this by simply calling it before the all gather.

Without this PR, I'm often running into:

           work = group.allgather([tensor_list], [tensor])
E       ValueError: Tensors must be contiguous
