I can't believe I made such a stupid pasto and the regression test

PR target/121634
gcc/
* config/loongarch/simd.md (simd_maddw_evod_<mode>_<su>): Use
WVEC_HALF instead of WVEC for the mode of the sign_extend for
the rhs of multiplication.
gcc/testsuite/
* gcc.target/loongarch/pr121634.c: New test.

Bootstrapped and regtested on loongarch64-linux-gnu. Ok for trunk?
