target/loongarch: Fix the cpu unplug resource leak
When the cpu is created, qemu_add_vm_change_state_handler
is called in the kvm_arch_init_vcpu function to create
the VMChangeStateEntry resource.
However, the resource is not released when the cpu is destroyed.
This results in a qemu process segment error when the virtual
machine restarts after the cpu is unplugged.
This patch solves the problem by adding the corresponding resource
release process to the kvm_arch_destroy_vcpu function.

migration: Avoid SNP guest crash due to duplicate cpr blocker
With aux-ram-share=off, booting an SNP guest fails with:
../util/error.c:68: error_setv: Assertion `*errp == NULL' failed.
This is because a CPR blocker for the guest_memfd ramblock is added
twice, once in ram_block_add_cpr_blocker because aux-ram-share=off so
rb->fd < 0, and once in ram_block_add for a specific guest_memfd blocker.
To fix, add the guest_memfd blocker iff a generic one would not be
added by ram_block_add_cpr_blocker.
Fixes: 094a3dbc55df ("migration: ram block cpr blockers")

Revert "target/riscv/kvm: add missing KVM CSRs"
This commit breaks KVM boot on older kernels, like reported in [1], due
to senvcfg not being available in them.
There's also another problem related to scounteren. Using a recent
enough guest buildroot, 'ping' will be build with rdtime support. In
this case, doing a ping in a KVM guest while exposing scounteren will
result in an error. The root cause relates to how KVM handles
scounteren, but QEMU can work around it by initializing scounteren with
the host value during init().
Fixing these issues in a non-rushed-bandaid manner results in an amount
of design changes that I don't feel comfortable pushing during code
freeze, so for 10.0 we'll remove the CSRs and re-introduce them in 10.1
with the adequate support.
This reverts commit 4db19d5b21e058e6eb3474b6be470d1184afaa9e.
