-RISCV: Illegal instruction delegated to VS mode sets the wrong vscause value
-Description of problem:
-When delegating an illegal instruction exception caused in VS-mode to VS-mode, the vscause value for an illegal instruction is set incorrectly.
-
-Steps to reproduce:
-1. Delegate 2(,6,10) in medeleg and hedeleg.
-2. Enter VS-mode
-3. Cause an illegal instruction fault, cause 6 can't happen in QEMU since there is misaligned support and 10 can't be delegated to VS mode.
-4. The (v)scause CSR is then set to 1, i.e. instruction access fault which isn't correct.
-
-I have located the issue in the code @ cpu_helper.c:1703
-```
-if ((cause == IRQ_VS_TIMER || cause == IRQ_VS_SOFT ||
-    cause == IRQ_VS_EXT)) {
-    cause = cause - 1;
-}
-```
-
-The if statement should include a check for the async otherwise the cause shouldn't be altered. The patch I propose is simply to **and** the current statement with async.
-```
-if (async & (cause == IRQ_VS_TIMER || cause == IRQ_VS_SOFT ||
-    cause == IRQ_VS_EXT)) {
-    cause = cause - 1;
-}
-```
-Additional information:
-Log where the incorrect cause is set. Note this line: `DEBUG: [src/trap_handling.c: 105] Instruction access fault exception: SEPC = 0x80008850, STVAL = 0x0`
