riscv: use mret to invoke M-mode payload and disable interrupts
Fixes a logic error that sets MPIE, but didn't use mret to return to the payload.
This left MIE set to an undefined value.
Now all modes are handled the same way:
- Trap vector base address point to the payload
- Disable Interrupt
- Return to payload using mret
TEST=Run an M-mode payload
