RISC-V: KVM: Mark the reset callback of FWFT extension always dirties CSR

Browse Source 
As the CSR is only flushed when the csr_dirty is set, always set the
csr_dirty field in kvm_sbi_ext_fwft_reset() so the CSR change can take
effect immediately. This unconditional set should be safe as all
supported FWFT features change the CSR state currently.
