During the review of commit 1ff2f0fa450e ("net/mlx5e: Return in default
case statement in tx_post_resync_params"), Leon and Nick pointed out
that the switch statements can be converted to single if statements
that return early so that the code is easier to follow.

v1 -> v2:

* Refactor switch statements into if statements

v2 -> v3:

* Rebase on net-next after v1 was already applied, patch just refactors
  switch statements to if statements.
