Fix editing error introduced in 9e7b406

I added an extraneous sentence to the non-normative text in one of the
two instructions.

 These branch-based semantics do not prevent implementing this instruction as a simple select (e.g., "(rs2!=0) ? 0 : rs1").
 Instead, they allow for more sophisticated implementations where a zero-result can be returned when the condition (rs2!=0) is true without waiting for _rs1_ to be available.
 Furthermore, implementations can predict the condition just as they might for branches.
-However, the timing is independent of the data value in rs1.
 
 As a consequence of this instruction's equivalence to `mv rd, rs1` when _rs2_ is zero, this instruction's timing is independent of the data value of _rs1_ if the Zkt extension is implemented.
