target/xtensa: fix FPU2000 bugs

Browse Source 
- FPU2000 defines rfr and wfr opcodes, not rfr.s and wfr.s;
- movcond.s uses incorrect operand in tcg_gen_movcond: in case the
  condition is not satisfied it must not change its argument 0.

Fixes: c04e1692e3 ("target/xtensa: extract FPU2000 opcode
translators")
