nine: Fix assert in tx_src_param

A previous commit cleaned up the asserts but the last part of
this assert looks like it got mixed up. It should have allowed
param->rel for D3DSPR_INPUT if version is 3.0. Instead it does
&& on the enum value D3DSPR_ADDR which is of course always true,
with the version check. The result is that we miss input
validation with version 3.0.

Spotted by a compile warning
