net/octeontx2: set max VTAG insertion size

When TX side VTAG insertion is enabled, SMQ should be configured with
the maximum VTAG insertion size to avoid generating NIX_SQINT_SEND_ERR
interrupt. Since the default value is zero, This patch configures the
VTAG insertion size to the max supported value.
