brw: In "Clear Accumulator" workaround, never set predicate_inverse

Browse source 
Since there's no predicate, the inverse bit is not relevant, so always
set it to false instead of using whatever was set by the previous
instruction.  Hardware already ignores this but will make verifying
later changes easier.
