[Intel-wired-lan] [PATCH iwl-next] ice: improve error message for insufficient filter space

[Martyna Szapar-Mudlaw]

When adding a rule to switch through tc, if the operation fails
due to not enough free recipes (-ENOSPC), provide a clearer
error message: "Unable to add filter: insufficient space available."

This improves user feedback by distinguishing space limitations from
other generic failures.
