riscv: perf: add guest vs host distinction
When merging this PR into linus-next, I've started seeing build errors:

Looks like this is due to 2c47e7a74f44 ("perf/core: Correct perf
sampling with guest VMs") which went in couple of days ago through
Ingo's perf tree and changed the number of parameters for
perf_misc_flags().
