    PR target/98743: Fix ICE in convert_move for RISC-V

     - Check `from` mode is not BLMmode before call store_expr, calling
store_expr
       with BLKmode will cause ICE.

     - Verified with riscv64, x86_64 and aarch64, no introduce new regression.

    Note: Those logic was introduced by
3e60ddeb8220ed388819bb3f14e8caa9309fd3c2,
          so I cc Jakub for reivew.

    Changes for V2:

     - Checking mode of `from` rather than mode of `to`.
     - Verified on riscv64, x86_64 and aarch64 again.
