target/riscv: Fix hstatus.GVA bit setting for traps taken from HS-mode
Currently, QEMU does not set hstatus.GVA bit for traps taken from
HS-mode into HS-mode which breaks the Xvisor nested MMU test suite
on QEMU. This was working previously.
This patch updates riscv_cpu_do_interrupt() to fix the above issue.
Fixes: 86d0c457396b ("target/riscv: Fixup setting GVA")
