[net-next 10/15] net/mlx5e: Unindent the else-block in mlx5e_xmit_xdp_buff

[Saeed Mahameed <saeed@kernel.org>]

From: Maxim Mikityanskiy <maximmi@nvidia.com>

The next commit will add more indentation levels to mlx5e_xmit_xdp_buff.
To keep indentation minimal, unindent the else-block of the if-statement
by doing an early return.
