target/riscv: Correctly implement TSR trap
As reported in: https://bugs.launchpad.net/qemu/+bug/1851939 we weren't
correctly handling illegal instructions based on the value of MSTATUS_TSR
and the current privledge level.
This patch fixes the issue raised in the bug by raising an illegal
instruction if TSR is set and we are in S-Mode.
