    target/riscv: write back fsgnjn.h and fsgnjx.h results

    Under Zfinx/Zhinx, trans_fsgnjn_h() and trans_fsgnjx_h() compute their
    results into a temporary but return without calling gen_set_fpr_hs().
    The instructions consequently retire without updating the corresponding
    integer register. Add the missing writeback calls, matching
    trans_fsgnj_h().
