target/riscv: Fix target address to update badaddr

Compute the target address before storing it into badaddr
when mis-aligned exception is triggered.
Use a target_pc temp to store the target address to avoid
the confusing operation that udpate target address into
cpu_pc before misalign check, then update it into badaddr
and restore cpu_pc to current pc if exception is triggered.
