RISC-V: KVM: Split huge pages when dirty logging is enabled
Split huge pages eagerly when enabling dirty logging. The goal is to
avoid doing it while faulting on write-protected pages, which
negatively impacts guest performance.
The benefits of eager page splitting are the same as in x86 and arm64,
added with commit a3fe5dbda0a4 ("KVM: x86/mmu: Split huge pages mapped
by the TDP MMU when dirty logging is enabled") and commit e7bf7a490c68
("KVM: arm64: Split huge pages when dirty logging is enabled")
