RISC-V: KVM: Introduce make_xfence_request_nodata for FENCE.I requests

Browse source

FENCE.I does not need hfence data, but it currently goes through the
generic make_xfence_request() path with NULL data, incurring unnecessary
per-VCPU checks.

Split out a separate make_xfence_request_nodata() function to handle
FENCE.I directly, and move the data validity check to the top of the
generic function to avoid redundant checks.
