i965: Fix a mistake from porting the URB allocation code to arrays.
Commit 6d416bcd846a49414f210cd761789156c37a7b3e (i965: Use arrays in
Gen7+ URB code.) introduced a regression which caused us to fail to
allocate all of our URB space.
- total_wants -= ds_wants;
+ total_wants -= additional;
The new line should have been total_wants -= wants[i].
Fixes a large performance regression in TessMark.
