net/mlx5e: CT: 'update' rules instead of 'replace'

Offloaded rules can be updated with a new modify header action
containing a changed restore cookie. This was done using the verb
'replace', while in some configurations 'update' is a better fit.

This commit renames the functions used to reflect that.
