KVM: RISC-V: SBI FWFT: Mark vCPU CSRs dirty after setting feature value
Mark the vCPU CSRs as dirty after successfully setting an FWFT feature
value. FWFT features may modify CSRs (e.g., pointer masking modifies
henvcfg.PMM), and failing to mark them dirty can lead to the guest
observing stale CSR state after vCPU scheduling or migration.
