net/mlx5e: Fix MACsec initial packet number
Currently when creating MACsec object, next_pn which represents the initial packet number (PN) is considered only in TX flow. The above causes mismatch between TX and RX initial PN which is reflected in packet drops. Fix by considering next_pn in RX flow too.
