LoongArch: Clean up vec_init expander
Non functional change, clean up the code.
gcc/ChangeLog:
* config/loongarch/loongarch.cc
(loongarch_expand_vector_init_same): Remove "temp2" and reuse
"temp" instead.
(loongarch_expand_vector_init): Use gcc_unreachable () instead
of gcc_assert (0), and fix the comment for it.
