target/mips: Remove unused register from MSA 2R/2RF instruction format
Commits cbe50b9a8e7 ("target-mips: add MSA VEC/2R format instructions") and 3bdeb68866e ("target-mips: add MSA 2RF format instructions") added the MSA 2R/2RF instructions. However these instructions don't use any target vector register, so remove the unused TCG temporaries.
