KVM: selftests: riscv: Improve unexpected guest trap handling
Currently, we simply hang using "while (1) ;" upon any unexpected
guest traps because the default guest trap handler is guest_hang().
The above approach is not useful to anyone because KVM selftests
users will only see a hung application upon any unexpected guest
trap.
This patch improves unexpected guest trap handling for KVM RISC-V
selftests by doing the following:
1) Return to host user-space
2) Dump VCPU registers
3) Die using TEST_ASSERT(0, ...)
