[PATCH v2 2/8] target/riscv: Fix hstatus.GVA bit setting for traps taken from HS-mode

[Anup Patel]

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.
